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...
