Get a shop air compressor and charge it up full of air, say to 10 atmospheres. Disconnect it from power and wheel it onto a sensitive beam scale. Zero the scale. Open the tank valve slowly and let all the air escape. Record the new weight.

You should be able to get a good figure for the density of air from the pressure drop, the tank volume and the weight change.

Since this is where atmospheric pressure comes from. They don't need to weigh the airdirectly. They know the volume of the room and the density ofair at normal pressure and temperature is 1.225 kg per cubic metre. Multiply one by the other to get the mass of air.
