Title: finding volume of dry nitrogen at stp Post by: Subi08 on Apr 8, 2015 If 77.0 mL of nitrogen gas is collected over water at 50 °C and 763 mm Hg, what is the volume of dry nitrogen gas at STP? The vapor pressure of water at 50 °C is 92.5mm Hg. Title: Re: finding volume of dry nitrogen at stp Post by: bio_man on Apr 9, 2015 Hi Subi,
What have you done so far? I might be able to help if you show some work! :) Title: Re: finding volume of dry nitrogen at stp Post by: Subi08 on Apr 9, 2015 Hi Subi, What have you done so far?

STP = 1 atm of pressure and 273 K for temperature P = 1 atm V = ??? n = 1 mole R = 0.0821 atm L/mol K K = 273 K PV=nRT Title: Re: finding volume of dry nitrogen at stp Post by: bio_man on Apr 9, 2015 ^^ Not sure if that answers the question.
