Answer:

(a) The concentration of a solution is the amount of solute present in a given quantity of the solution.

(b) Given:

Mass percentage of solution = 20%

Mass of solution = 550 g

Mass of solute = m

Since mass percentage of solution = (mass of solute/ mass of solution) X 100

Therefore, Mass of Solute = (Mass percentage of Solution x Mass of Solution) / 100

Substituting the values we get

m = (20 x 550)/100

   = 110 g
