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