2.5 g of a solute are dissolved in 25 g of water to form a saturated solution at 298 K. Find out the solubility of the solute at this temperature. What mass of potassium chloride would be needed to form a saturated solution in 50 g of water at 298 K? Given that solubility of the salt is 46/100 g at this temperature.

Explanation

Mass of the solute = 2.5 g
Mass of the solvent = 25 g
Solubility of the solute = `("Wt. of the solute")/("Wt. of the solvent") xx 100`
` = (2.5 )/(25 ) xx 100 =10`
