The solubility of salt in hot solvent is 75 gm and in cold solvent is 25 gm.
When a saturated solution containing 75 gm of salt is cooled, $75 - 25 = 50$ gm of salt is settled.
When 1.5 gm of saturated salt solution is cooled, the amount of salt settled is $\frac{50}{75} \times 1.5 = 1$ gm

The solubility of a salt at 40oC is 25gm and at 100oC it is 75gm. A saturated solution of 1.5gm of the salt is cooled from 100oC to 40oC. How much salt settle down?5gm1gm0.3gm1.2gm

The solubility of salt in hot solvent is 75 gm and in cold solvent is 25 gm. When a saturated solution containing 75 gm of salt is cooled, 75−25=50 gm of salt is settled.When 1.5 gm of saturated salt solution is cooled, the amount of salt settled is 5075×1.5=1 gm

The solubility of a salt at $40^{o} C$ is $25 g m$ and at $100^{o} C$ it is $75 g m$ . A saturated solution of $1.5 g m$ of the salt is cooled from $100^{o} C$ to $40^{o} C$ . How much salt settle down?
$5 g m$
$1 g m$
$0.3 g m$
$1.2 g m$

The solubility of salt in hot solvent is 75 gm and in cold solvent is 25 gm.
When a saturated solution containing 75 gm of salt is cooled, $75 - 25 = 50$ gm of salt is settled.
When 1.5 gm of saturated salt solution is cooled, the amount of salt settled is $\frac{50}{75} \times 1.5 = 1$ gm
