The observed value of dipole moment of `H_(2)O`
molecule is found to be 1 .84 D. Calculate the
`H-O-H` bond angle in `H_(2)O` molecule ,
given that the bond moment of O-H bond is 1.5 D.

Explanation

To calculate the H-O-H bond angle in the H₂O molecule using the given dipole moments, we can follow these steps:

### Step 1: Understand the Dipole Moment
The dipole moment (μ) of a molecule is a vector quantity that depends on the individual bond dipole moments and their angles. For H₂O, we have two O-H bonds contributing to the overall dipole moment.

### Step 2: Define the Given Values
- Observed dipole moment of H₂O (μ) = 1.84 D
- Bond dipole moment of O-H (μ_OH) = 1.5 D
