If you collect 350.0 mL H2 gas over water at 90.0 C and under 115.4 kPa of pressure, what will the dry gas volume be at STP? (water vapor pressure at 90.0 degrees C is 70.1 kPa)
looks like just PV=nRT problem.. do they give you this information?
(water vapor pressure at 90.0 degrees C is 70.1 kPa)
what does the exact question read?
It looks like the vapor pressure from the water would be deducted from the total pressure of the water vapor if that information is given to you.. I'm trying to remember why or how to use that information, I am not in Chemistry right now, doing Physics and Calc..
