Question

Ammonia gas is passed into water, yielding a
solution of density 0.93 g/cm3 and containing
18.6% NH, by weight. The mass of NH3 per cc of
the solution is
(1) 0.17 g/cm3
(3) 0.51 g/cm3
(2) 0.34 g/cm3
(4) 0.68 g/cm3

solve it​

Answer 1

Density =

volume

mass

Mass = density × volume

Density = 0.93g/cc

Mass of 1 cc of solution =0.93×1=0.93g

The solution contains 18.6% ammonia by weight.

So, 1 cc of solution =18.6% of 0.93g ammonia

=

100

18.6×0.93

= 0.173 g/cm
