How much water should be added to 12g glucose to obtain 20% glucose solution

Answer 1

hey mate here is your answer

if you want to make a total solution of 500 ml of 20 percent glucose, multiply (20/100) by 500. The answer is 100, so you need 100 g of powdered glucose. (If you were making a 10 percent glucose solution, the calculation is (10/100) x 500, and the answer is 50 g)

it will surely help you.
