How much work is done by the system when
2.00 moles of O2 expand from a volume of
3.00 liters to a volume of 9.6 liters against a constant external pressure of 0.0100 atm
answer in units of joules

    w = -pdV
    Work done by the system is -
    pdV is 0.01*(9.6-6.6)

    where did you get the 6.6 from? and i did the work correctly and the answer was wrong.

  • AP Chemistry - ,

    I typed in the wrong number. That's V2-V1 = (9.6-3.00) so
    work = -0.01*6.6 = ? in L*atm since 0.01 is in atm and delta V is L. The problem asks for joules. Convert L*atm to Joules.
    1 L*atm = 101.325 joules.

    This may be a little late but what about moles
