a$.$ The table below shows the major ions found in a mineral water. For each ion, calculate it's concentration in equivalents per liter $($as shown in the last column$).$ Report your results in the column or in a table of your own in the work you submit.

b$.$ Does this ionic composition match charge balance expectations? If not, report the imbalance as a percentage of the total ionic charge represented by these major ions. Stated another way, find the charge imbalance in eq$/$L$,$ find the total charge due to cations and add it to the total charge due to anions $($using absolute values$)$ in eq$/$L$,$ and express the imbalance as a percentage of the total. In general, if the percentage is $5\%$ or less, the imbalance is more likely due to measurement precision than additional types of ions that were not analyzed. Please answer the attached question.
