Solubility of `KNO_(3)`at 313 K is 62 g. What mass of `KNO_(3)` would be needed to produce a saturated solution of `KNO_(3)` in 50 g of water at 313 K ?

Text Solution

Verified by Experts

By definition of a saturated solution.
100 g of water at 313 k contain `KNO_(3) = 62 g`
50 g of water at 313 K contain `KNO_(3) = 31 g`
