1256 torr. If the partial pressures are 555 torr for O2 and 143
torr for He, what is the partial pressure in atm of the nitrogen in
the mixture?

A 9.60-L container holds a mixture of two gases at 27 °C. The
partial pressures of gas A and gas B, respectively, are 0.370 atm
and 0.645 atm. If 0.220 mol of a third gas is added with no change
in volume or temperature, what will the total pressure become?

A 9.40-L container holds a mixture of two gases at 45 °C. The
partial pressures of gas A and gas B, respectively, are 0.181 atm
and 0.780 atm. If 0.100 mol of a third gas is added with no change
in volume or temperature, what will the total pressure become?
