The density of air, is the mass per unit volume of Earth's atmosphere. In the SI system it is measured as the number of kilograms of air in a cubic meter (kg/m3). At sea level and at 20 °C dry air has a density of approximately 1.2 kg/m3. varying with pressure and temperature.
0.001 cubic meter = 1 liter. So....1.2 kg/cubic meter = 0.0012 kg/L, or 833.3 L/kg. With 1 kg of air, this means 833.3 L is the approximate volume.

Try PV=nRT
Solve for the only variable that isn't given and then convert the moles to grams /kilograms.

Use PV = nRT, the ideal gas law.
