    Hey that mol question for phosphorous oxide... I got like 1053kg
    Then 49.2% yield, the one above with PV=nRT I got 0.113m3
    C3O8C2HC

    Erm... I didn't have enough time to balance the equations! Also, I got 28.something for the Mr

    I put 49.2 for percentage yield
    And I got 0.451m3
    Cos it's 101 000 pascals, 773K

    Same.

    Did you get the empirical formula as Ca3C2O8H2?

    i got a big number like 1065000 too but my Percentage yield was something like 23% since i thought you couldn't use moles to calculate H2S04's mass since it was aqueous?

    I didn't bracket it though. For the volume question did you get 0.451m3 by any chance?
