Calculate the concentration of `K^(o+)` (x) and `Cl^(ɵ)` (y) in a solution obtained by mixing 20 " mL of " 0.1 M `NaCl`, 30 " mL of " 0.2 M KCl, and 25 " mL of " 0.15 M `KNO_3` and making the solution up to 100 mL.
(a). `x=0.06,y=0.0375`
(b). `x=0.0975, y=0.08`
(c). `x=0.08,y=0.08`
(d). `x=0.08,y=0.0375`

Explanation

To find the concentration of \( K^+ \) (x) and \( Cl^- \) (y) in the solution obtained by mixing the given solutions, we will follow these steps:

### Step 1: Calculate the millimoles of \( NaCl \)
- Volume of \( NaCl \) solution = 20 mL
- Concentration of \( NaCl \) = 0.1 M

\[
\text{Millimoles of } NaCl = \text{Volume (L)} \times \text{Concentration (M)} = 0.020 \, \text{L} \times 0.1 \, \text{mol/L = 2 \, mmoles}
