Question

guys what ppm and express the concentration of..​

Answer 1

Explanation:

Parts Per Million

Parts Per Million (ppm) is a measurement of the concentration of a soluton. For very dilute solutions, weight/weight (w/w) and weight/volume (w/v) concentrations are sometimes expressed in parts per million. 1 ppm is one part by weight, or volume, of solute in 1 million parts by weight, or volume, of solution.

Answer 2

Parts Per Million (ppm) is a measurement of the concentration of a soluton. For very dilute solutions, weight/weight (w/w) and weight/volume (w/v) concentrations are sometimes expressed in parts per million ppm is one part by weight, or volume, of solute in 1 million parts by weight, or volume, of solution.
