Question

calculate the mass of glucose required to make a solution of volume 250ml and the concentration of 40%​

Answer 1

Explanation:

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.
