Question

The theoritical yeild of a reaction that gives off nitrogen trifluoride gas is 844 mL at STP. What total volume of NF3 plus water vapor will be collected over water at 25° C and a total pressure of 1.017 atm?

Answer 1

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.
