**Water Quality Analysis**

A public utility announces the monthly average concentrations of several ionic species in the drinking water. The list is given below (atomic weights are given in parentheses):

- **Calcium (40):** 8.6 mg/L
- **Magnesium (24):** 0.77 mg/L
- **Potassium (39):** 0.64 mg/L
- **Sodium (23):** 3.7 mg/L
- **Chloride (35.5):** 3.0 mg/L
- **Fluoride (19):** 0.84 mg/L
- **Sulfate (S = 32; O = 16):** 3.4 mg/L

**pH = 8.46**

a) What is the ratio of \([ \text{HCO}_3^- ]/[ \text{CO}_3^{2-} ]\) in this water?
