Answer:
5200 ppm
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 = [tex]\frac{Lead}{Water} \times 10^6[/tex] = [tex]\frac{1.30}{250} \times 10^6[/tex] = 5200 ppm
So, as calculated above, there is 5200 ppm of lead present in 250 ml of water.
