Question

200 gm of saturated solution of certain salt gives 40 gm of salt when heated till its dryness. Calculate solubility at that temperature. ans fast

Answer 1

Answer:

180g

weight of salt = 90 gram,

solubility = 50

sing formula

solubility of solute =

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.
