The specific mass is 0.001204 at 1 atm, 20C, 0% humidity.
(The density is 1.204 mg/cm^3 or 0.0752 lb/ft^3.)
You can decide if you need to correct for pressure and temperature. Humidity will be a smaller correction that can alter the result by roughly 1% at normal everyday temperatures and pressures.

The mass of air depends on finding two other properties to define its state. A psychrometric chart is the best way to determine this. The mass can be found from temperature, humidity, pressure, enthalpy, etc.

13.75cubic ft. / lb. is the specific volume of standard air . i think the inverse is what youre looking for ..071 lbs/c.f. that # depends on the het and humidity though

air has no mass since it is not solid

Do you mean mass? Or do you mean weight?
Or don't you know the difference?
Most people don't.
