I don't get the "or reacted". I assume you want the volume of H2 corrected to STP.
Look up the vapor pressure of water at 10 C.
Ptotal = pH2O + pH2
105.5 = vap pressure H2O + pH2 and solve for pH2.
Then PV = nRT and solve for V.
Remember to use the same units for ptotal and vapor pressure of H2O at 10 C. Also, if you use P in kPa the R is 8.314. Also remember T must be in kelvin.
Some hydrogen is collected over water at 10 degrees C and 105.5 kPa pressure. The total volume of the sample was 1.93 L. Calculate the volume of the hydrogen or reacted to STP.

I am sorry I think autocorrect changed it to that. It is supposed to so corrected no or reacted.
Thank you so much.
