Question

Calculate the mass of glucose and mass of water required to make 200g of 25% solution of glucouse.​

Answer 1

Answer:

hiii

your answer is here !

Explanation:

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

follow me. !

Answer 2

Solution

concentration of glucose= 25%

mass of solute/mass of solution x 100 = 25

mass of solute/250 x 100 = 25

mass of solute = 25/100 x 250 =62.5 g
