if 2.5g of a solute are dissolved in 25g of water to form a saturated solutio at 298 K,the solubility of the solute is____

The amount of the solute present in saturated solution at a particular temperature is called its solubility at that temperature. It is usually measured as the amount of solute present per 100 g of the solvent at a given temperature. We are given that 2.5g of solute is dissolved in 25g of water at 298 K to prepare a saturated solution. Thus

mass of solute present in 25g of water = 2.5g

mass of solute present in 1g of water = (2.5/25) g

mass of solute present in 100g of water = [(2.5 X 100) / 25] g = 10 g

Thus, the solubility of the solute at 298 K is 10 g per 100 g of water.
