Question #187193

ii. A mass of gas is stored in a cylinder. The gas is stored at a pressure of 1.2 MPa and the cylinder has a volume of 0.03 m3 and temperature of 100 oC , Find the mass of the gas.

The characteristic gas constant for air is 300 Jkg−1K−1.

Expert's answer

Given:

Pressure (P)=1.2 MPa = 1.2 x10^{6} Pa

Volume (V)= 0.03 m^{3}

Temperature (T)= 100 ^{o}C=373 K

The characteristic gas constant for air (R) = 300 Jkg−1K−1.

**To Find :**

Mass of the gas(M)

**Solution :**

Assuming air as an ideal gas , It obeys ideal gas equation P.V=M RT

Mass (M) of air is given by

0.322 kg
