Didn't I do a similar one for you yesterday.
Find total mols gase
Find mole fraction (XN2) of N2.
Then pN2 = XN2*Ptotal.
A sealed container comtains 1.50 mol of nitrogen gas, 2.00 mol of oxygen gas and 3.50 mol of argon gas. If the total pressure is 900 kPa, what is the pressure of the nitrogen gas?
I don't know which formula to use

The problem is i don't understand the mole fraction
mol fraction N2 = mol N2/total mols.
and if you want mol fraction of the others it is
XAr = mols Ar/total mols
XO2 = mols O2/total mols.
and if you want mol fraction of the others it is
XAr = mols Ar/total mols
XO2 = mols O2/total mols.
