Question

The density of an aqueous solution of ammonia
is o.9 gml-1 and is 27% by weight.Calculate the molality and molarity of the solution
of ammonia .​

Answer 1

Answer:

21.75mol/kg and 14.3mol/L

Answer 2

Answer:

For 25 wt% (NH3) at 20 ºC; ρ = 0.907 g/cm3 (interpolated). The molecular mass of NH3 is 17.03 g/mol. Hence, the molarity in terms of NH3 would be: 0.25(g NH3 / g aq.
