Question

class: 9 Roll Noils DATE: / 120 A solution contains 50g of com common salt in 4200 of waters Calculate the concentration in terms of mass by mass percentage of the solution. solution: Mass of solute (salt) 50 Mass of (solvant) solvent a water) = H2O 50g at 24 20g 11​

Answer 1

Answer:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g
