Problem

A 4.55 L sample of solution contains 0.115 g of sodium ions. Determine the concentration of sodium ions in ppm if the density of the solution is 1.00 g/mL.

A. 52.3 ppm

B. 13.2 ppm

C. 12.7 ppm

D. 25.3 ppm

E. 36.5 ppm

Solution

We’re being asked to calculate the concentration of sodium ions (Na+) in ppm in the sample solution. 

Let’s first define ppm and ppb.


1 ppm means 1 part of solute for every 106 parts of the solution

Can be written as:

ppm=mass of solutemass of solution×106


1 ppb means 1 part of solute for every 109 parts of the solution
