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

Explanation

To find the normality of a 1.5 M solution of \( H_3PO_4 \) (phosphoric acid), we can follow these steps:

### Step 1: Understand the relationship between Molarity and Normality
Normality (N) is related to molarity (M) by the formula:
\[ N = M \times n \]
where \( n \) is the number of equivalents of the solute. For acids, \( n \) is the number of hydrogen ions (H\(^+\)) that can be donated per molecule of acid.
