Question

calculate the mass of water and mass of glucose required to make 250g of 40 percent solution of glucose

Answer 1

We know that,

Mass percent = mass of solute / mass of solution

Here mass of solution = 250g

Mass of solute = X

Mass percent = 40

Hence 40% = X/250

Therefore X = 100g

Hence amount of solute needed to make 250g of 40% solution is 100g

As we know mass of solution = mass of solute + mass of solvent,

Therefore mass of solute = 250g – 100g

Hence the mass of solute = 150g
