Question

6grms of urea was dissolved in 500 g of water calculate the percentage by mass of urea in the solution

Answer 1

Explanation:

Urea=16gm.

water=39gm.

total mass solution=16+39=55gm.

so if you get 16gm.of urea in 55gm.of the solution.It follows that 100gm.of this solution will contain=100×16/55=29gm. urea

Thus the solution contains 29gm.of urea.
