Question

You have prepared a solution by dissolving 73.15mg of sucrose (table sugar, C12H22O11) in 1.55kg of water. What is this solution's sucrose concentration in parts per million, ppm? (show steps)

Answer 1

(Value in ppm)/1 000 000= mass of solute/mass of solution

Value in ppm= [(73.15x10^-3)/1550]x 1 000 000

Value in ppm=47.194= 47.2 ppm (3 significant figures).
