A gaseous mixture of O2, H2, and N2 has a total pressure of 1.50 atm and contains 8.20 g

Question

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!

Answer 1

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.
