What is the volume of 176 g of carbon dioxide under normal conditions?

Given:

m (CO2) = 176 g,

V (CO2) -?

Decision:

The volume is determined by the formula:

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

1. Let’s calculate the amount of CO2 substance.

n = m: M, where M is the molar mass of the substance.

n (CO2) = Ar (C) + 2 Ar (O) = 12 + 2 × 12 = 44 g / mol.

n (CO2) = 176 g / mol: 44 g / mol = 4 mol.

2. Let’s calculate the volume of carbon dioxide:

V (CO2) = 4 mol × 22.4 L / mol = 89.6 L.

Answer: V (CO2) = 89.6 liters.
