Calculate the volume of carbon dioxide produced by the complete combustion of 2.4 g of carbon.

1.Let’s find the amount of carbon by the formula:

n = m: M.

M (C) = 12 g / mol.

n = 2.4 g: 12 g / mol = 0.2 mol.

2. Let’s compose the equation of the reaction of carbon combustion.

C + O2 = CO2.

1 mole of carbon accounts for 1 mole of carbon dioxide. They are in quantitative ratios of 1: 1. The amount of carbon and oxygen will be the same.

n (CO2) = 12 g / mol.

3. Let’s find the volume of carbon dioxide.

V = Vn n, where Vn is the molar volume of gas, equal to 22.4 l / mol, and n is the amount of substance.

V = 22.4 L / mol × 0.2 mol = 4.48 L.

Answer: 4.48 liters.
