The solubility of common salt in water at 293K is 36g. The mass ( in g ) of common salt needed to make a saturated solution in 20g water at 293 K is `"________________"`.

Text Solution

Verified by Experts

The correct Answer is:
7.2
Amount of sodium chloride ( common salt ) needed for making saturated solution in 100g of water = 36g
`:.` Amount of common salt in 20g of water `= ( 36)/( 100) xx 20`
`= 7.2g`
