A 5000 cm3 tank contains an ideal gas of molar mass 40gmol

- A 5000 cm³ tank contains an ideal gas of molar mass 40g/mol at a gage pressure of 530Kpa and a temperature of 25C. Assuming atmospheric pressure to be 100Kpa, what mass of gas is in the tank?                                                   

Solution

gas constant

R=R_U/M=8.314/40=0.208 KJ/kg-K

Mass of gas is

m=PV/RT =(530+100)*(5000*10^-6)/0.208*(273+25)

m=0.0508 kg =0.051 kg

m=
