Question

If the solubility of a substance in a solvent is X what is the minimum weight of solution containing y gram of solute

Answer 1

Answer:

weight of salt = 90 gram,

solubility = 50

sing formula

solubility of solute =

weightofsolventinsaturatedsolution

weightofsoluteinsaturatedsolution ×100or 50=

weightofsolventinsaturatedsolutio

90gm×100

so weight of solvent in saturated solution = 5090gm×100=180gm

Hence 180 gm of water is required to prepare a saturated solution.
