Answer: Mass of solute (sodium chloride) =36g
Mass of solvent (water) =100g
Mass of solution = Mass of Solute + Mass of solvent
= 36g +100g = 136g
= mass of solute X 100 = 36 X 100 = 26.47 %
mass of solution 136
26.47 % is the answer
Mass of solvent (water) =100g
Mass of solution = Mass of Solute + Mass of solvent
= 36g +100g = 136g
= mass of solute X 100 = 36 X 100 = 26.47 %
mass of solution 136
26.47 % is the answer
