Question

If we have 40 g of salt and need to make a solution of concentration 20% then the mass of water required would be pls answer

Answer 1

Explanation:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40=360 g

concentration of solution= massofsolutionM

mass ofsolute ×100* 360

40 ×100=11.11%

Hence, the concentration of the solution is 11.11%
