Answer:100 g glucose, 150 g water
Explanation: A/q, 100 g solution has 40 g glucose. Hence 250 g solution has 40x250/ 100= 100 g glucose.
250-100= 150 g water

We know Mass percent = mass of solute / mass of solution Here mass of solution = 250g Mass of solute = ? Mass percent = 40 Hence 40 % = X/ 250 ? X= 100g Hence amount of glucose needed to make 250g of 40 % solution of is 100 g As we know Mass of solution = mass of solute + mass of solvent Therefore Mass of Solvent = 250g – 100g Hence the mass of solvent(water)= 150g
