CO (5.00 g)and CO₂ (5.00 g)were placed in a 750.0 mL container at 50.0 °C.The total pressure in the container was ________ atm.

Question

Quizplus · Accepted Answer

The correct answer is A because the total pressure in the container is the sum of the partial pressures of CO and CO2. The partial pressure of CO is 5.00 g / 28.01 g/mol * 0.0821 Latm/(molK) * 323 K / 750.0 mL * 1000 mL/L = 0.292 atm. The partial pressure of CO2 is 5.00 g / 44.01 g/mol * 0.0821 Latm/(molK) * 323 K / 750.0 mL * 1000 mL/L = 0.146 atm. The total pressure is 0.292 atm + 0.146 atm = 0.438 atm.
