solution what is the solubility of this salt in 100g of the solvent at 25°c?​

Answer 1

Answer:

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.
