Question

how many litre of 15 % sugar solution would take it to get 75 gram of sugar

Answer 1

So we want a solution which has 15% of sugar concentration

So let no. of litres of water be x

So now the solution is 75 + x

Now,

15%( 75+ x) = 75

75 + x = 75 * 100/15

x = 500 - 75

x = 425litres

Answer 2

total solvent = 75 g
total solution = 15 % = 15 \ 100
total concentration = total solute*100/total solvent
= 1136.3 litre answer.
