A gaseous mixture of O2, H2, and N2 has a total pressure of 1.50 atm and contains 8.20 g
of each gas. Find the partial pressure of each gas in the mixture
They don't give you Volume and Temperature. Please explain it to me, thank you!

  You want to convert 8.2 g O2 to moles, 8.2 g N2 to moles, 8.2 g H2 to moles.
  Then determine the mole fraction of each.
  partial pressure each = Xof each*1.5 atm.
  moles fraction, O2 for example, = moles O2/total number of moles.
