Calculate what is the mass of carbon dioxide, the volume of which is 5.6 liters.

Chemical formula of carbon dioxide: CO2.
1) Molar mass of carbon dioxide: 12 + 16 * 2 = 44.
2) Using the formula n = V / Vm, we find the amount of carbon dioxide. Vm – molar volume equal to 22.4 liters. n = 5.6 / 22.4 = 0.25 mol.
3) Using the formula m = M * n, we calculate the mass of the gas. M is molar mass. m = 44 * 0.25 = 11g.
Answer: the mass of carbon dioxide, which under normal conditions takes 5.6 liters is equal to 11 g.
