At 0*C a 1.0-L flask contains 5.0 x 10^-2 mol N2, 1.5 x 10^2 mg O2, and 5.0 x 10^21 molecules of NH3. What is the partial pressure of each gas, and what is the total pressure in the flask?

  • chemistry -

    mols N2 = 5E-2.
    mol O2 = 0.15/molar mass = ?
    mol NH3 = 5.0E21/6.02E23 = ?
    Use PV = nRT and mols of each to find partial pressure of each gas. Add partial pressures to find total pressure.
