Question

9. A solution is prepared by adding 50 g o f copper sulphate in 100 g of water. Calculate the concentration in terms of mass-by-mass percentage of solution.​

Answer 1

Answer:

Step-by-step explanation:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=

×100=11.11%

Hence, the concentration of the solution is 11.11%

Answer 2

Answer:

50/150×100 = 100/3 and 100/150×100 = 200/3
