Concentrated aqueous ammonia contains 1.00 mol NH3 dissolved in 2.44 mol H20. What is the mole fraction of NH3 in concentrated aqueous ammonia? What is the molal concentration of NH3

  • Chemistry - ,

    mol fraction = (mols NH3)/(mol NH3 + mol H2O) = 1.00/3.44 = ??

    molal = mols/kg soln.
    molal = 1/(2.44 x 18 g/mol x 1 kg/1000 g) =
    check my thinking. Check my work.
