Calculate the mass of water and mass of glucose required to make 250g of 40% solution of glucose??
pls answer as soon as possible!!!!!!!
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.
