AI Generated Solution

To solve the problem of calculating the quantities of reagents required to soften \(10^3\) L of water containing \(Ca(HCO_3)_2\), \(Mg(HCO_3)_2\), and \(CaSO_4\), we will follow these steps: ### Step 1: Calculate the total mass of each impurity in \(10^3\) L of water. 1. **For \(Ca(HCO_3)_2\)**: \[ \text{Mass} = 20.0 \, \text{g/L} \times 10^3 \, \text{L} = 20000 \, \text{g} \] ...
