    I have a chemistry test tomorrow and I can't seem to get the right answer.
    I used this formula: PV=nRT for both and I'm still getting the answer wrong.
    6. At what temp. does 5.00g of H2 occupy a volume of 50.0L at a pressure of 1.01 atm? (1.01)(50.0)=(2.5)(8.31)(T)
    7. How many moles of gas would you have if you had a volume of 38.0 L under a pressure of 1432 mmHg at standard temp? (1432)(38)=(n)(8.31)(273)
    Am I even setting these up right?

    For the second question, you have to convert the 1433mm Hg to Pascal units.
    Use this converter

    Then find out the answer.
