A sample of nitrogen gas is collected over
water at a temperature of 23°C. What is the pressure of the nitrogen gas if the atmospheric pressure is 791 mm Hg?
Answer in units of mm Hg

  • Chemistry -

    Ptotal = pN2 + pH2O
    791 = Ptotal
    pH2O--look up vapor pressure H2O at 23 C and substitute. Then solve for pN2.
