There are on average 43 g of sugar and 355 mL can of soda please calculate the molarity of sugar in the can of soda the molar mass of sugar is 342.2 g/mol

Answers

Answer 1

Explanation:

Given :

Amount of solute - sucrose (C12H22O11) = 41 g

Amount of solvent -soda  = 355-mL

Molarity of the solution with respect to sucrose= ?

Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.

Formula to find the molarity of solution :

               Molarity =  

Amount of solvent is given in mL, let’s convert to L :

               1 L = 1000 mL

Therefore, 355 mL in L will be :

                   

               = 0.355 L

We have the amount of solute in g, let’s calculate the number of moles first :

       Number of moles (n) =  

Molar mass of C12H22O11 = 342.29 g/mol.

Therefore, n =  

               = 0.119 moles.

5. The coefficients are: 2, 7, 2, 4

6. The coefficients are: 1, 4, 1, 2

Explanation:

5. Balancing the equation.

__NO₂ + __H₂ —> __NH₃ + __H₂O

The above equation can be balance as illustrated below:

NO₂ + H₂ —> NH₃ + H₂O

There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 2 before NO₂ and 4 before H₂O as shown below:

2NO₂ + H₂ —> NH₃ + 4H₂O

There are 2 atoms of N on the left side and 1 atom on the right side. It can be balance by writing 2 before NH₃ as shown below:

2NO₂ + H₂ —> 2NH₃ + 4H₂O

There are 2 atoms of H on the left side and a total of 14 atoms on the right side. It can be balance by writing 7 before H₂ as shown below:

2NO₂ + 7H₂ —> 2NH₃ + 4H₂O

Now the equation is balanced. Thus, the coefficients are: 2, 7, 2, 4

6. Balancing the equation:

__SiO₂ + __HF —> __SiF₄ + __H₂O

The above equation can be balance as illustrated below:

SiO₂ + HF —> SiF₄ + H₂O

There are 4 atoms of F on the right side and 1 atom on the left side. It can be balance by writing 4 before HF as shown below:

SiO₂ + 4HF —> SiF₄ + H₂O

There are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

SiO₂ + 4HF —> SiF₄ + 2H₂O

Now the equation is balanced. Thus, the coefficients are: 1, 4, 1, 2

What is the predicted change in the boiling point of water when 2.10 g of
barium chloride (BaCl2) is dissolved in 5.50 kg of water?

Answers

The addition of any non-volatile solutes will elevate the boiling point of the solution. The change in boiling point of water by the addition of 2.10 of barium chloride is 0.0028 ° C. Hence, option A is correct.

What is boiling point?

Boiling point of a substance is the temperature at which it changes from liquid to vapour where the two states are in equilibrium. Boiling point of a substance depends on the bond type, molecular mass and purity of it.

The change or elevation of boiling point of a solution can be determined from its molality m and elevation constant Kb and the Van't Hoff factor i as follows:

ΔT = i Kb m.

Molality of the solution is the no.of moles divided by the mass of solvent in kilogram. Given the mass of barium chloride is 2.10 g and its molar mass is 208.23 g . The no.of moles of solute is 2.10/208.23 g = 0.0100.

Molality of the solution can be calculated as follows:

Molality m = 0.0100 / 5.50 Kg

                 = 0.0018 mol/kg.

Now, the  ΔT s calculated from these values. Provided Kb of water is 0.51 ° C /mol and i = 3.

ΔT  = 0.0018 mol/kg × 0.51 × 3

       = 0.0028 ° C.

Therefore, water will boil at 100.0028 ° C. Hence, option A is correct.

Explanation:

According to this question, sulphur dioxide (SO2) reacts with oxygen to produce sulphur trioxide (SO3). The equation is as follows:

SO2 + O2 → SO3

The above equation is unbalanced because there are unequal number of atoms of each element in the both reactants and products. To balance the equation, we use coefficients to make the number of atoms equal. The balanced equation is as follows:

2SO2 + O2 → 2SO3

- There are 2 moles of S on both sides of the equation.

A student made a sketch of a potential energy diagram to represent an endothermic reaction.


Explain, using complete sentences, why the diagram made by the student is correct or incorrect. Be sure to also explain what the values of X and Y represent. (10 points)

Answers

Answer:

Incorrect

Explanation:

X is the reactants

Y is the products

In an endothermic reaction where energy is absorbed, the enthalpy the products (Y) is always higher than the enthalpy of the reactants (X).

Enthalpy change (∆H) = products (Y) - Reactants (X)

For an endothermic reaction, the ∆H value should be positive.

Enthalpy change

The diagram sketched by the students shows the opposite. The diagram shows that the enthalpy of the products (Y) is lower than the enthalpy of the reactants (X). This will give a negative value of ∆H.

It represents an exothermic reaction rather than endothermic.

Therefore, the student is incorrect.

What is the mass of 0.125 moles of tin sulfate (SnSO4)?

Answers

Answer:

26.85 grams

Explanation:

The formula for mole calculations is number of moles = given mass/gram-formula mass.

The number of moles is given to us, which is 0.125.

The gram formula mass of SnSO4 is about 214.77.

Plug in the values we have into the equation. It should look like this:

0.125 = x / 214.77

Solve for x by multiplying 214.77 and 0.125. The answer should be about 26.85 grams.

b. 3.33
c. 10.1
d. 10.7

Answers

Answer:

1) b. 4.38

2)  d. 10.7

Explanation:

1) The problem tells us that [H₃O⁺] = 4.2x10⁻⁵ M, and keeping in mind that [H₃O⁺]= [H⁺], we can calculate the pH of the solution:

pH = -log[H⁺] = 4.38

2) First we calculate the pOH of the solution:

pOH = -log[OH⁻] = -log(4.6x10⁻⁴) = 3.33

Then we calculate the pH using the following formula:

pH = 14 - pOH = 14 - 3.33pH = 10.7

The pH of a solution with a concentration of 4.2x10⁻⁵ M H₃O⁺ ion is 4.38 and of a solution with a concentration of 4.6x10⁻⁴ OH⁻ ion is 10.7.

What is pH and pOH?

pH of any solution is define as the negative log of the concentration of H⁺ ions and pOH is define as the negative log of the concentration of OH⁻ ions.

Given that concentration of H⁺ ions in solution = 4.2x10⁻⁵ M

pH for this solution is calculated as:
pH = -log(4.2x10⁻⁵) = 4.38

Also given that concentration of OH⁻ ions in solution = 4.6x10⁻⁴

pOH = -log(4.6x10⁻⁴) = 3.33

We know that, pH + pOH = 14.

pH = 14 - 3.33 = 10.7

Hence, value of pH & pOH is 4.38 and 10.7 respectively.

A 217.6 sample of gas is collected at 9.011 atm and 127.8°C. What volume does the gas have at 44.9 atm and 11.9 °C?M

Answers

Answer:

The correct answer is = 31.04

Explanation:

The relation between volume, temperature and pressure of a fix amount of a gas can be expressed by the combined gas law:

PV/T = k

It can be written as well as

P1V1/T1 = P2V2/T2

Given:

V1 = 217.6

P1 = 9.011 atm

T1 = 127.8°C = 400.95 K

P2 = 44.9

T2 = 11.9 °C = 285.05

Solution:

Putting value in the formula

V2 = P1V1T2/P2T1

= (217.6*285.05*9.011)/44.9*400.95

V2 = 31.04
