Question

A vessel of volume V = 30 litres contains ideal gas at S.T.P. After a portion of the gas has been let out, the pressure in the vessel decreased by P=0.78 atm (the temperture remaining constant).
Find the mass of the released gas. The gas density under the normal conditions is p = 1.3 gm/litre.

Answer 1

Answer:

A vessel of volume V = 30l contains ideal gas at the temperature 0°C. A vessel of volume V = 30l contains ideal gas at the temperature 0°C. After a portion of the gas has been let out, the pressure in the vessel decreased by Δp = 0.78 atm (the temperature remaining constant)
