At 0.00 degrees C a 1.00 L flask contains 5.00 x 10^-2 mol N2, 1.50 x 10^2 mg O2, and NH3 at a concentration of 5.00 x 10^18 molecules/mL. What is the partial pressure of each gas, and what is the total pressure in the flask at atm?

Convert mg and molecules to mols.
mols N2 you have.
mols O2 = grams/molar mass = ?
mols NH3 = #molecules/6.02E23 = ?

Use PV = nRT and solve for each pressure.
Then total P = sum of partial pressures.
