The Correct Option is A
Solution and Explanation
Formula:
$$
\text{Molarity} = \frac{\text{Moles of Solute}}{\text{Volume of Solution (in liters)}}
$$
Substituting values: $$ \text{Molarity} = \frac{5}{2} = 2.5 \, \text{M} $$
Substituting values: $$ \text{Molarity} = \frac{5}{2} = 2.5 \, \text{M} $$
