If you have a 17% salt solution, how much salt will need to be added to 71 mL of water?

Salt added : 14.5 g

Given

17% salt solution

71 ml water

Required

salt needed

Solution

%mass = (mass solute : mass solution) x 100%

71 ml water = 71 g water(density = 1 g/ml)

mass solute = x

the dissolution of polymer can be thermodynamically described in 2 steps.
