Question

A reading reports that the amount of Cl present in a local swimming pool is 1.8g. If it contains 600,000g of solution, what is the concentration of Cl in parts per million?

Answer 1

Solution.

$w(Cl) = \frac{m(Cl)}{m(sol)}$

$w(Cl) = \frac{1.8}{600,000} = 3 \ ppm$

Answer:

w(Cl) = 3 ppm
