Answer:
weight of salt = 90 gram,
solubility = 50
sing formula
solubility of solute =
weightofsolventinsaturatedsolution
weightofsoluteinsaturatedsolution
×100
or 50=
weightofsolventinsaturatedsolutio
90gm
×100
so weight of solvent in saturated solution =
50
90gm
×100=180gm
Hence 180 gm of water is required to prepare a saturated solution.

Answer: Mass of sodium chloride (Solute) = 40gm
Mass of water (solvent) = 250 gm
Mass of solution = 40+250 = 290gm
Concentration = (Mass of Solute / Mass of Solution) * 100
Concentration = (40/290)*100 = 13.79%
Concentration of solution is 13.79%.
Hope it helps you buddy...
