What is the number of chloride ions (Cl-) in 250 mL of a 0.2M magnesium chloride solution?

a. 0.1 mol c. 0.62 mol
b. 0.16 mol d. 1.6 mol

Answers

Answer 1

According to molar concentration and mole concept, there are 0.1 mole of chloride ions in 250 mL of a 0.2 M magnesium chloride solution.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.

By substituting values in given formula, number of moles=0.2×0.250=0.05 moles .Now this values is subtracted from molar mass of magnesium chloride  that is 95.211-0.05=95.161 moles which is finally divided by 95.211=0.999 which is approximately 0.10 mole.

What is mass percentage composition ?

We use the concept of mass percentage composition to explain the concentration of an element in a compound or a component in a combination. This word refers to the overall percent by mass of each element present in a compound.

In chemistry, a compound's percent composition is calculated by dividing its total amount of each elements by the compound's total amount, multiplied by 100. The following formula determines an element's percentage composition:

What is rate constant?

Rate of a reaction is the rate of decrease in concentration of the reactants or increase in concentration of the products. The rate is directly proportional to the concentration of reactants and the rate law is written as:

rate = k [reactants]

where, the proportionality constant k is called the rate constant.

The order of a reaction is the sum of powers of the molar concentration of reactants. Thus, each reaction vary in order and the order of reaction also depends on the steps in the reaction.

The general formula of the unit of rate constant is L⁽ⁿ⁻¹⁾ mol⁽¹⁻ⁿ⁾ s⁻¹. Hence,  first reaction is a first order reaction and the unit of rate constant is s⁻¹. The second one is also a first order reaction with the same unit.

Given the half-life of the radioactive sample of an isotope of bromine to be 16.5 hours. The amount of time it takes for 3/4 of a radioactive sample of an isotope of bromine to decay is calculated as follows:

After one half-life, half of the sample remains, and half decays

The mass of [tex]IF_5[/tex] that would be in a 15.88 L sample at 378 K and 0.935 will be 106.51 grams.

Ideal gas problem

The problem can be solved by first using the ideal gas equation to know the number of moles of the gas that is present.

PV = nRT

P = 0.935, V = 15.88 L, T = 378 K, R = 0.082

Making n the subject of the formula:

n = PV/RT

  = (0.935x15.88)/(0.082x378)

   = 0.48 moles of the gas

Recall that, mass = mole x molar mass

The molar mass of [tex]IF_5[/tex] is 221.89 g/mol

Mass of 0.48 moles [tex]IF_5[/tex] = 0.48 x 221.89
