what is the pressure of H2 if the hydrogen gas collected occupies 14L at 300K and was produced upon reaction of 4.5 mol of Al?

  • chemistry -

    PV=nRT

    now to n...
    2Al+3H2SO4>> Al2(SO4)3 + 3H2
    which would indicate 4.5*3/2 moles H2

    But what if the acid were HCl?
    2Al+ 6HCl>>2AlCl3 + 3H2
    moles of H2: 4*3/2 again.
