Dear student
The mass percentage of a solution is defined as

width="413">
Where, mass of a solution = Mass of solute + Mass of solvent
We are given that the sugar solution is 2 5 % and the mass of
solution is 500g Let y grams be the mass of sugar (solute) present
in 500g of solution Therefore
2 5 = (y / 500) X 100
This gives y = 12 5
Therefore mass of water (solute) = mass of solution - mass of
sugar (solute)
= (500 - 12 5) g
= 487 5 g
Hence 487 5 g of water would be required
