Explanation:
As per the definition, parts per million of a contaminant is a measure of the amount of mass of contaminant present per million amount of the solution. It is denoted by ppm.
Given in the question,
Water = 250 ml = 250 g
Lead = 1.30 g
So,
ppm of Lead =
=
= 5200 ppm
So, as calculated above, there is 5200 ppm of lead present in 250 ml of water.
