A certain quantity of a gas occupied `100ml` when collected over water at `15^(@)C` and `750mm` pressure . It occupies `91.9ml` in dry state at `NTP`. Find the `V.P.` of water at `15^(@)C`

Explanation

To solve the problem of finding the vapor pressure of water at 15°C, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Volume of gas collected over water (V1) = 100 ml
- Pressure of moist gas (P1) = 750 mm Hg
- Temperature (T1) = 15°C = 288 K (converted to Kelvin)
