Question

to make a saturated solution of pottasium permanganate 36g of crystals dissolved in 120g of water calcute the concentration of the solution

chemistry class 9

Answer 1

By mass /mass percentage
Solute = 36g
solution= solute +solvent = 36 + 120 = 156g

Mass of solute / mass of solution×100.
36/156 ×100, 18 /78 ×100 , 9/39× 100 ,3/13×100 = 300/13. or 23.076....
