Calculate the mass of water and mass of glucose required to make 250g of 40% solution of glucose??

pls answer as soon as possible!!!!!!!

We know

Mass percent = mass of solute / mass of solution

Here mass of solution = 250g

Mass of solute = ? 

Mass percent = 40 

Hence 40 % = X/ 250

∴ X = 100g 

Hence amount of solute 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 Solute = 250g - 100g 

Hence the mass of solute = 150g.
