Solution

## The correct option is C Mass of glucose = 125g, Mass of water = 375g Given mass of solution (M) = 500g Concentration of solution = 25% Since, Mass by Mass percentage of solution = [Mass of solute (m)/Mass of solution (M)] × 100 ⇒ 25 = m500×100 ⇒ m = 25100×500 = 125g ⇒ Mass of solute = 125 g Mass of solvent (water) = M - m = 500g - 125g = 375 g  Suggest Corrections  0      Similar questions
