Ammonia gas is passed into water, yielding a solution of density 0.93 gram/cm3 and containing 18.6% NH3 by weight. The mass of NH3 per cc of the solution is___?

Let 100 gram solution is taken.M=V×d where M is mass of solution,V is volume of solution and d is density of solution.Vsolution=Md=100 gram0.93 gram/cm3=107.5cm3mass of NH3 per c.c=18.6107.5=0.17298 gram/cm3=0.17gram/cm3mass of NH3 per c.c=18.6107.5=0.17298 gram/cm3=0.17gram/cm3
