Question

A solution contain 50g of comman salt in 300g of water calculate the concentration in term of mass by mass percentage of the solution

Answer 1

Answer:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+ 40 =360 g

concentration of solution=

mass of solution / mass of solute ×100

360 / 40 ×100=11.11%

Hence, the concentration of the solution is 11.11%
