Question

Ammonia gas is passed into the water leading the solution of

Answer 1

Explanation:

Most probably, it is .........

NH3 + H20 ------> NH4OH

Answer 2

Applying,

Density = Mass/Volume

Hence Mass = Density x Volume

Density = 0.93g/cc

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

1 cc of solution =0.93g

Solution contains 18.6% ammonia by weight.

                               = (18.6/100) x 0.93 = 0.173g

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

So mass of ammonia per cc of solution is 0.173g.
