Question

if 15gm of saturated formed on 30०C is cooled down to 10०c then how much salt can be produce? solubility of salt on 30०c and 10०c are 95 and 30 respectively.​

Answer 1

Answer:

plese mark me brainlist

Explanation:

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.
