A mixture of gases contains 0.65 mol of N2, 0.70 mol of O2, and 0.90 mol of He.

What is the partial pressure of each gas (in atm and in torr) in a 25.0 L cylinder at 340 K?

What is total pressure?

I know you:
Use mols each gas in PV = nRT and solve for p.
Then Ptotal = pN2 + pO2 + pHe

So do the steps.
