Question

what mass of glucose is required to make 20% of 100 ml water solution

Answer 1

100ml of water means 100 g of water as it's density is 1 gm/ml
now
let the mass of glucose is x
then
$\frac{x}{100 + x} = \frac{20}{100} \\ 100x = 20x + 2000 \\ 80x = 2000 \\ x = 25$
hence 25 gm of glucose is required
