Question

350ml of a certain gas has mass 0.05g at 550 degree centigrade at 0.2 bar pressure.Find molar mass of the gas.​

Answer 1

Explanation:

PV=nRT

n=mass/molar mass

hence molar mass m=MRT/PV

====================================

numerically

m=(0.05 X 8.314 X 923)/ 350 x 0.2      (here 923 by converting centigrate to kelvin)

m=5.48 g/mole
