Question

Flask A contains 0.5 L of Ar gas at 1.5 bar and 0 oC, and flask B contains 300 mL of N2 gas at 700 torr and 100 oC. After the two gases are mixed together in a 0.4 L flask at 298 K, what are the partial pressures of the two gases and the total pressure of the gas inside the flask? Assume ideal gas behaviour. Show your calculations.

Answer 1

1bar = 750torr

700/750= 0.933bar

1.5+0.933= 2.433bar

100+273= 373k

373×2.433× 800= 400× 298× P2

726007.2= 119200p2

P2 = 6.091bar
