Question

The concentration of a solution can be expressed in

(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

Answer 1

(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

Answer 2

(2) parts per million

Step-by-step explanation:

Concentration of a solution can be expressed in terms of parts-per-million (ppm).

ppm is usually used in the context of measuring very small concentrations particularly the amount of contaminants. It represents 1 part of the contaminant in 100000 parts of the total.

It is expressed as:

1 ppm = 1 mg / L

1 ppm = 1 mg/ Kg
