Calculate The Mass Of Glucose And Mass Of Water

By
Q43: Calculate the mass of glucose and mass of water required to make 200g of 25% solution of glucose. 

Answer:  
Given mass of solution(M) = 200g Concentration of solution = 25%
Since, Mass by Mass percentage of solution =
mass of solute(m) × 100 / mass of solution(M).

⇒ 25 = m × 100/200g
⇒ m = 25 × 200/100 = 50g 

∴ mass of solute = 50g mass of solvent 
(water) = M - m = 200g - 50g = 150g
