What is the mass of 1.5 moles of carbon dioxide? How much will this amount of substance take?

Find the molar mass of carbon dioxide:

M (CO2) = A (C) + 2A (O) = 12 + 2 * 16 = 44 g / mol;

The mass of carbon dioxide can be found by the formula:

m (CO2) = n (CO2) * M (CO2) = 1.5 * 44 = 66 g;

Under normal conditions, 1 mol of gas occupies a volume of 22.4 liters.

V (CO2) = 22.4 * 1.5 = 33.6 liters.

Answer: m (CO2) = 66 g; V (CO2) = 33.6 l.
