For example, water samples from water, one of the lead contaminated with อยู่ร้ less 2 x 10 - 4 by mass
g, calculates the intensive unit. Ppm B. shall determine the concentration in the unit ppb
how to do it.Determine the concentration in the unit ppm
from formula ppm (mass) = (mass / mass of solute solution) x 10 6
from solving the masses of the melt. = 2 x 10 - 4 mass of solution = 100
instead of ppm (mass) = (2 x 10 - 4 / 100) x 10 6
= 2
B. shall determine the concentration in the unit. Ppb
.From the formula ppb (mass) = (mass / mass of solute solution) x 10 9
from solving the mass of solute = 2 x 10 - 4 mass of a = 100
. Instead of ppb (mass) = (2 x 10 - 4 / 100) x 10 9
= 2 000,,
