Question

What kind of plant growth hormone to regular plant growth. We dissolve 5.0 mg of the solution into 2.0 kg of water. What is the dosage of the solution in ppm? _ppm

Answer 1

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:

$p.p.m. = \frac{5\,mg}{2000000\,mg}\times 1000000$

$p.p.m. = 2.5\, ppm$

The dosage of the solution is 2.5 parts per million.
