Answers

Answer 1

The number of moles of each atom present in 5 moles of Cu₃(PO₄)₂ are:

15 moles of Cu10 moles of P40 moles of O

Description of Cu₃(PO₄)₂1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu2 moles of P(2×4) = 8 moles of O

How to determine the mole of each atom

The moles of atom present in 5 moles of Cu₃(PO₄)₂ can be obtained as follow

For Cu

1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu.

Therefore,

5 moles of Cu₃(PO₄)₂ will contain = 5 × 3 = 15 moles of Cu

For P

1 mole of Cu₃(PO₄)₂ contains 2 moles of P.

Therefore,

5 moles of Cu₃(PO₄)₂ will contain = 5 × 2 = 10 moles of P

For O

1 mole of Cu₃(PO₄)₂ contains 8 moles of O.

Therefore,

5 moles of Cu₃(PO₄)₂ will contain = 5 × 8 = 40 moles of O

Answer 2

The number of moles of copper, phosphorous and oxygen present in the 5 moles of Cu₃(PO₄)₂ are 15, 20 and 40 respectively.

What is stoichiometry?

Stoichiometry of any chemical equation gives idea about the amount of species present before and after the reaction.

Dissociation reaction of Cu₃(PO₄)₂ is shown as below:
Cu₃(PO₄)₂ → 3Cu²⁺ + 2PO₄³⁻

From the stoichiometry of the equation, it is clear that:

1 mole of Cu₃(PO₄)₂ produces 3 moles of copper atom, 2 moles of phosphorous atoms an 8 moles of oxygen atom.

5 moles of Cu₃(PO₄)₂ = produces 3×5=15 moles of Cu

5 moles of Cu₃(PO₄)₂ = produces 2×5=10 moles of P

5 moles of Cu₃(PO₄)₂ = produces 8×5=40 moles of O

Hence required moles of copper, phosphorous and oxygen are 15, 20 and 40 respectively.

A gas has a mass of 3.82 g and occupies a volume of 0.854 L. The temperature in the laboratory is 302 K, and the air pressure is 1.04 atm. calculate the molar mass of the gas.

1) 93.4 g/ mol
2) 72.3 g/ mol
3) 107 g/ mol
4) 35.8 g/mol

Answers

The molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

How to calculate molar mass?

The molar mass of a substance can be calculated by dividing the mass of the substance by its number of moles.

However, the number of moles of the gas in this question needs to be calculated first using the ideal gas law equation:

PV = nRT

Where;

P = pressureV = volumen = number of molesT = temperatureR = gas law constant

1.04 × 0.854 = n × 0.0821 × 302

0.888 = 24.79n

n = 0.888/24.79

n = 0.036mol

Molar mass of gas = 3.82g/0.036mol

Molar mass = 106.66g/mol

Therefore, the molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.

A quantity of helium gas occupies 5 liters at room temperature and standard atmospheric
pressure (760 mm Hg). If the temperature stays the same, what will be the volume o
the helium if the pressure is increased to 950 mm of mercury?

Answers

The new volume of occupied by helium gas when its pressure is increased from 760 mm Hg to 950 mm Hg at an initial volume of 5 L is equal to 4 L.

Boyle's Law

Boyle's law state that at constant temperature, the volume of a fixed mass of gas is directly proportional to its pressure.

To calculate the volume of the helium gas, we use the formula below.

Formula:

P₁V₁ = P₂V₂............. Equation 1

Where:

P₁ = Initial pressureV₁ = Initial volumeP₂ = Final pressureV₂ = Final volume.

Make V₂ The subject of the equation

V₂ = P₁V₁/P₂............... Equation 2

From the question,

Given:

P₁ = 760 mm HgV₁ = 5 LP₂ = 950 mm Hg

Substitute these values into equation 2

V₂ = (760×5)/950V₂ = 4 L.

Hence, The new volume of occupied by helium gas when its pressure is increased from 760 mm Hg to 950 mm Hg at an initial volume of 5 L is equal to 4 L.

Answers

The moles of water are used in the given reaction between CO₂ & H₂O is 12 moles.

How do we calculate mass from moles?

Mass of any substance will be calculated by using their moles as:

n = W/M , where

W = given or required mass

M = molar mass

Given chemical reaction is:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Moles of 528 g of CO₂ = 528g / 44.01g/mol = 11.99 moles

From the stoichiometry of the reaction, it is clear that:

6 moles of CO₂ = reacts with 6 moles of H₂O

So, 11.99 moles of CO₂ = reacts with 11.99 = 12 moles of H₂O
