A 7.35-L container holds a mixture of two gases at 17 °C. The partial pressures of gas A and gas B, respectively, are .415 atm and .720 atm. If .160 mol of a third gas is added with no change in volume or temperature, what will the total pressure become?
Dalton's law of partial pressures states that in a gaseous mixture, the pressure exerted by a component is the same as the pressure it would exert if it alone occupied the container.
Since pressures are additive, and we know
