Question

Calculate the amount of sugar required to prepare a solution 35% concentration mass by volume in 250 gram of water. Density of water 1.02 ​

Answer 1

Explanation:

98% by weight of solution means 98g of H

2

SO

is present in 100g of solution.

Volume of solution =

density of solution

mass of solution

=

(1.8×1000)g/L

100g

Volume of solution =
