Question

Ammonia gas is passed into water,yielding a solution of density 0.93g/cm³and containing 18.6%ammonia by weight.The mass of ammonia per cc of the solution is

Answer 1

Thanks for asking the question!

ANSWER::

Density = Mass/Volume
So, Mass = Density * Volume
 Density = 0.93g/cc
Mass of 1 cc of solution ={0.93 * 1 }= 0.93g
 1 cc of solution =0.93g
 Solution contains 18.6% ammonia by weight.
 So,1 cc of solution =18.6% of 0.93g ammonia= (18.6/100) * 0.93 = 0.173g
So, this comes the mass of ammonia per cc of solution which is 0.173g.

Hope it helps!

Answer 2

Answer:

Explanation:

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.

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

= (18.6/100) x 0.93 = 0.173g

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