Question

If sugar solution 20% (w/ w) find (
w/v)if density is 1.2 g/ m

Answer 1

Answer:24% w/v

Explanation:

20% w/w sugar solution means 20g of sugar is present in 100g of solution.

Density of solution= 1.2g/ml

Volume of solution= mass of solution/density of solution

= 100g/1.2g/ml

= 100/1.2 ml

Now,( 100/1.2)ml of solution contain 20g of solute.

So, 100mlof solution contain (20g/100/1.2ml)×100ml = 24g

Hence, 24% w/v is the answer.
