An apparatus consists of a 4 L flask containing nitrogen gas at 32C and 885 kPa, joined by a valve to a 8 L flask containing argon gas at 32 C and 47.5 kPa. The valve is opened and
the gases mix. What is the partial pressure of nitrogen after mixing?
Answer in units of kPa

  • AP chem - ,

    Effectively all you are doing is letting the N2 gas in the 4L container expand to a total of 12 L so the pressure of the N2 gas will be
    885 x 4/12 = ? kPa.
