50 . Three canisters, A, B, and C, are all at the same temperature, with volumes of 2.0, 4.0, and
6.0 liters, respectively. Canister A contains 0.976 g of argon gas at a pressure of 120 torr,
canister B contains 1.37 g of nitrogen gas at a pressure of 210 torr, and canister C is
completely empty at the start. Assuming ideality, what would the pressure become in
canister C if the contents of A and B are completely transferred to C?
