Gas is confined in a tank at a pressure of 11.5 atm and a temperature of 22.0°C. If two-thirds of the gas is withdrawn and the temperature is raised to 60.0°C, what is the pressure of the gas remaining in the tank?
The final moles of the gas is,
N2 = (1/3)N1
Use the ideal equation to find the pressure of the gas.
P2/P1 =(N2/N1) *(T2/T1)
Thus, the final pressure of the gas is,
P2 =(N2/N1) *(T2/T1)*P1
=(1/3)* [(60+273) K / (22 + 273) K] (11.5 atm)
= 4.327 atm
= 4.3 atm
