mass percentage = 25%
mass of solvent = 250g
Mass percent = mass of solute / mass of solvent * 100
mass% = 25%
mass of solvent = 250g
25% = mass of solute / 250*100
=25*2500/100
=6250/100
mass of salute = 62.5g
Mass of Water = mass of solution - mass of solute = 250 - 62.5g
= 187.5g
Ans: Mass of glucose = 62.5g
Mass of water = 187.5g
