Elevation in boiling point studies of `Ca(NO_(3))_(2)` gives molar mass as `131.2`. The degree of dissociation of `Ca(NO_(3))_(2)` is
a.`100%` , b.`75%` , c.`50%` , d.`12.5%` ,

Explanation

To solve the problem regarding the degree of dissociation of \( Ca(NO_3)_2 \), we will follow these steps:

### Step 1: Write the dissociation equation
The dissociation of calcium nitrate can be represented as:
\[ Ca(NO_3)_2 \rightarrow Ca^{2+} + 2NO_3^{-} \]
