Question

Considering air as a 4:1 mixture of nitrogen and oxygen the mass of air in a hsll with dimensions 5m × 5m× 5m at stp

Answer 1

Answer:

here is the answer

since the temperature is not given

I consider it as 15°C

at 15°C density of air is 1.225kg/m^3

density=mass/volume

mass =density×volume

volume of the cube is 5×5×5m^3=125m^3

mass of the air =125×1.225 kg

=153.125 kg

I hope this is the answer $$
