The density of carbon dioxide is equal to 1.977 kg m-3 at 273 K and 1

1.	The density of carbon dioxide is equal to 1.977 kg m-3 at 273 K and 1 atm pressure. Calculate the molar mass of CO2
Answer» Molecular mass = Density x Molar volume Molar volume of CO₂ = 2.24 x 10^-2 m³ Density of CO₂ = 1.977 kg m^-3 Molecular mass of CO₂ = 1.977 x 10³ gm^-3 x 2.24 x 10^-2 m³ = 1.977 × 10 × 2.24 = 44 g

The density of carbon dioxide is equal to 1.977 kg m-3 at 273 K and 1 atm pressure. Calculate the molar mass of CO2

Answer»

Molecular mass = Density x Molar

volume Molar volume of CO₂ = 2.24 x 10^-2 m³

Density of CO₂ = 1.977 kg m^-3

Molecular mass of CO₂ = 1.977 x 10³ gm^-3 x 2.24 x 10^-2 m³

= 1.977 × 10 × 2.24

= 44 g
