Question

A gas has a density of 0.824 g/L and occupies a volume of 3.00 liters. What is the mass in grams?

Answer 1

Density is mass per unit volume,

ρ = m/v

Solving for mass gives

m = ρv

so that a gas with density 0.824 g/L that occupies 3.00 L has a mass of

m = (0.824 g/L) (3.00 L) = 2.47 g
