Question

how find the weight of air?

​

Answer 1

Answer:

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

Answer 2

As an example let us calculate air density of dry air at sea level in international standard atmosphere conditions of pressure (1013.25 hPa or 101325Pa) and temperature (15oC).

Remember that to convert oC to oK you need to add 273.15.

Density = 101325 / (287.05 * (15 + 273.15)) = 1.225 kg/m3
