A 8.90-L container holds a mixture of two gases at 45 C. The partial pressures of gas A and gas B, respectively, are .294 atm and .860 atm. If .100 mol of a third gas is added with no change in volume or temperature, what will the total pressure become?
if the partial pressure of the diatomic gas is .300 atm, what is the total pressure? 6 blue dots 5 orange dots 3 green dots consisting of 2 dots each (diatomic gas)
