A container has two gases at 27^oC, one with molar volume 6 L/mole, another with molar volume 3 L/mole, what is the total pressure of the container?(a) 6.9 atm(b) 8.5 atm(c) 12.3 atm(d) 15.8 atmThis question was addressed to me in quiz.Asked question is from Ideal Gas Mixtures and Partial Pressure topic in chapter Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer»

The correct CHOICE is (C) 12.3 atm

The best EXPLANATION: P1V1 = n1RT1, => p1 = 0.0821*300/6 = 4.1 atm, p2 = 0.0821*300/3 = 8.2 atm, => P = 4.1 + 8.2 = 12.3 atm.
