An apparatus consists of a 2 L flask containing
nitrogen gas at 25C and 819 kPa, joined by
a valve to a 12 L flask containing argon gas
at 25C and 51 kPa. The valve is opened and
the gases mix. What is the partial pressure of
nitrogen after mixing?
Answer in units of kPa



What is the partial pressure of argon after
mixing?
Answer in units of kPa


What is the total pressure of the gas mixture?
Answer in units of kPa

    for the first one i did 2 divided by 14 times 819 and got 116.99 but i don't know how to do the other two problems

    PN2 is right.
    Why wouldn't you do pAr the way way.
    51 x (12/14) = ?

    Total P = pN2 + pAr
