Question

the solubility of salt in water at 75 degree celsius is 155. when 80 g of its saturated solution of 75 degree celsius was cooled to 15 degree celsius, 40 grams of salts was crystallized out. the solubility of salt at 15 degree celcius is

Answer 1

Answer:

Explanation: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.
