Q)

Match the column-I and column-II

 Column-I Column-II (1) Molarity (p) Equivalent per liter (2) Normality (q) does not have units (3) ppm (r) moles per liter (4) Molality (s) moles per kg

$\begin{array}{1 1}(a)\;(1)\rightarrow (p),(2)\rightarrow (r),(3)\rightarrow (q),(4)\rightarrow (s)\\(b)\;(1)\rightarrow (q),(2)\rightarrow (p),(3)\rightarrow (r),(4)\rightarrow (s)\\(c)\;(1)\rightarrow (s),(2)\rightarrow (p),(3)\rightarrow (q),(4)\rightarrow (r)\\(d)\;(1)\rightarrow (r),(2)\rightarrow (p),(3)\rightarrow (q),(4)\rightarrow (s)\end{array}$

Toolbox:
• $Molarity =\large \frac{\text{Moles of solute}}{\text{Volume of solution in Litres}}$
• $Molality =\large \frac{\text{Moles of solute}}{\text{Mass of solvent in kg}}$
• The normality of a solution is the gram equivalent weight of a solute per liter of solution.
• parts per million = $\large \frac{\text{grams of solute}}{\text{grams of solution}} \times 10^6$
The unit of the properties listed in Column I is enlisted below:
Molarity $\rightarrow$ moles/lit
Normality $\rightarrow$ Equivalent/lit
Molality $\rightarrow$ moles/kg
ppm $\rightarrow$ does not have units
Hence (d) is the correct answer.
