Air has an approximate molar mass of (28x.8 + 32x.2) = 28 + .2x4 = 28.8 g/mole
1 mole of gas at STP occupies 22.4 L = 22400 cm3 = 0.0224 m3
So 28.8 g/mole x 1 mole/.0224 m3 = 1286 grams per cubic meter at STP
If you take 'normal temperature' to be room temperature of about 20 degrees C then
1286 x (273/293) = 1198 grams per cubic meter at standard pressure and 20 C

How heavy a cubic meter of gas?
A cubic metre of gas at normal temperature and pressure has a mass of 44.643 times the molecular weight of the gas in grams. So a cubic metre of hydrogen is 89.3 grams while a cubic metre of CO2 is 1964 grams. If the volume is 22.4 litres, the mass in grams equals the molecular weight.
