🤓 Based on our data, we think this question is relevant for Professor Ghosh's class at GS.
We’re being asked to determine the molarity of lead (Pb) in a 9.0-ppb solution. Let’s first define ppm and ppb.
• 1 ppm means 1 part of solute for every 106 parts of the solution
in terms of solutions:
• 1 ppb means 1 part of solute for every 109 parts of the solution
The maximum allowable concentration of lead in drinking water is 9.0 ppb.
Calculate the molarity of lead in a 9.0- ppb solution.
