To find:
Total mass of ions in

Answer to Problem 8.17QA
Solution:
Total mass of ions in
Explanation of Solution
1) Concept
To determine the mass of the solute needed to prepare a solution, we need to calculate the moles of the solute. We can calculate the moles of the solute from the molarity of the solution and volume.
A mole is the SI unit of an amount of chemical substance. When writing in units, it is written as “mol.”
2) Formula
