Solution

To make the salt solution of 15% with 15 gm as the mass of the solute, the mass of the solvent must be 85 gm.

`"concentration" = "mass of solute"/"mass of solute + mass of solvent"xx 100`

Mass of solution = mass of solute + mass of solvent
Mass of the solvent = mass of the solution – mass of solvent
= 100 – 15 = 85 gm
Therefore, 85 gm of water should be added.
