The correct answer is 0.25 g per gram of water.Concept:Solution: A homogenous mixture of two or more substances. It has two components solute and solvent. Solute: The substance that is dissolved in the solvent. Solvent: The substance in which solute is dissolved. For example, in a salt solution, salt is solute and water is solvent. Explanation:Solubility: The maximum amount of a solute that can be dissolved in 100 g of a solvent at a specified temperature is known as the solubility of that solute in that solvent (at that temperature).Given: Mass of sugar (solute) = 62.5 gMass of water (solvent) = 250g Solubility = (Mass of solute / mass of solvent) À” 100 = \(\frac{62.5}{250} À” 100\)= 25 % or 25/100 = 0.25 g per gram of water
