chem. Combined Gas laws
A gas takes up a volume of 17 liters, has a pressure of 2.3 atm, and a temperature of 299K. If I raise the temperature to 350K and lower the pressure to 1.5 atm, what is the new volume of the gas? Use the combined gas law here. I will be happy to critique your work.

Yes, when the problem says "dry" you subtract the vapor pressure of water AT THAT TEMPERATURE. How do we get that vapor pressure? We look it up in a table. The vapor pressure of water at 25 degrees C is 23.8 mm Hg. So 760-23.8 is the pressure of the dry gas (the other 23.8 is ...

A 9.80-L container holds a mixture of two gases at 39 C. The partial pressures of gas A and gas B, respectively, are 0.426 atm and 0.832 atm. If 0.250 mol a third gas is added with no change in volume or temperature, what will the total pressure become?

8.10-L container holds a mixture of two gases at 45 C. The partial pressures of gas A and gas B, respectively, are 0.153 atm and 0.882 atm. If 0.110 mol a third gas is added with no change in volume or temperature, what will the total pressure become?

Subtract the vapor pressure of water from total pressure, that yields the partial pressure of the gas. Now you have temp, partial pressure, use the combined gas law to find the new volume.
