Answer:
The dosage of the solution is 2.5 parts per million.
Explanation:
The solvent proportion in parts per million is equal to the ratio of solution in miligrams to ratio of water in miligrams multiplied by a million. (A kilogram is equivalent to a million miligrams) That is:
[tex]p.p.m. = \frac{5\,mg}{2000000\,mg}\times 1000000[/tex]
[tex]p.p.m. = 2.5\, ppm[/tex]
The dosage of the solution is 2.5 parts per million.
