Calculate the amount of lime and soda required for the softening of `10^(6)` L of a sample of boiler feed water with the following data:
`CaCO_3=1.4^@` Clark, `MgCO_3=0.56^@` Clark, `CaSO_4=0.42^@` Clark, `MgSO_4=0.14^@` Clark, `MgCl_2=0.035^@` Clark, and `NaCl=0.035^@` Clark.

Explanation

To solve the problem of calculating the amount of lime and soda required for the softening of \(10^6\) L of boiler feed water, we will follow these steps:

### Step 1: Convert Clark degrees to ppm (parts per million)
The conversion factor from Clark to ppm is given as \(1 \text{ Clark} = 0.07 \text{ ppm}\). Therefore, we will convert the given concentrations of impurities from Clark to ppm.

- For \( \text{CaCO}_3 = 1.4 \text{ Clark} \):
\[
\text{CaCO}_3 \text{ in ppm} = \frac{1.4}{0.07} = 20 \text{ ppm}
