what volume will be occupied by 3.25mol of oxygen gas at 735mmhg and 25celcius?

  • chemisty -

    Note how to spell celsius.
    Note that you start sentences with a capital letter. Don't try to make this a texting board.
    Use PV = nRT. n = 3.25. Remember that T MUST be in kelvin and P should be in atmospheres.
    735 mm Hg = 735/760 atm.
