Question

Compare the density of CO2 at 0 o C and 380 torr with its density at STP

Answer 1

The density of any gas can be estimated by the given equation,

density at STP = molar mass (1 mol / 22.4 L)

The molar mass of CO2 = 44.01 g/mol

The density of CO2 gas at STP = (44.01 g/mol) x (1 mol/22.4 L)

The answer is 1.96 g/L = 1.96 kg/m^3
