Question

2.
In an Aqueous solution of urea (NH,CONH2) is 20% (w/w) by mass of
solution . Calculate the molarity of the solution when the density of
the solution is 1.2 g/ml​

Answer 1

Answer:

Answer 2

The answer is 3.4M

Explanation:

Density = Mass / volume

1.02 = 100 / volume of solution

= 98.03 ml

Molarity = Mass of urea \ molecular mass of ures × volume of solution in litre

= 20 × 1000/ 60 × 98.03

= 3.4M
