The normality of `1.5M H_(3)PO_(4)` is-

Explanation

To find the normality of a 1.5 M solution of H₃PO₄ (phosphoric acid), we can follow these steps:

### Step 1: Understand Normality
Normality (N) is defined as the number of equivalents of solute per liter of solution. It can be calculated using the formula:
\[ \text{Normality (N)} = \text{Molarity (M)} \times \text{Valency Factor} \]

### Step 2: Identify Molarity
From the question, we have:
...
