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

Answer 1

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.

Answer 2

22.7 mol/kg
