Question

30% weight by volume of urea. what is the mass of solvent.

​

Answer 1

Answer:

30%(w/v) of urea means 30g pf urea in 100ml of solution.

Weight Of solution Is=Volume Of solution × Density of Solution.

Weight Of Solution=100×1.2=120g

Now, weight of solvent=weight of solution-weight of solute

So, weight of solvent=120–30=90g
