What is the molar mass of a compound if a gaseous sample has a density of 2.807 g/L at 18 °C and 728 torr?

  • Chemistry -

    = 728/(2.807)(0.08206)(291.15)
    =10.855 g

    ?

  • Chemistry -

    P*molar mass = density*RT
    Solve for molar mass.

  • Chemistry -

    Nope. P must be in atmospheres. 728/760 = ? atm.
    Also it appears to me you have set up the reciprocal.
    M = dRT/P
