Question

What is the concentration in ppm of Cu²⁺ in a 3 x 10^-4 in the aqueous CuSO₄ solution?

Answer 1

Parts per million, or ppm, is a measure of the amount of a substance per million parts of a solution.

1 ppm = 1 part "substance X"/ 1 x 106parts solution
1 ppm = 1 g X/ 1 x 106 g solution
1 ppm = 1 x 10-6 g X/ g solution
1 ppm = 1 μg X/ g solution
