A certain gas occupies `0.418 `litre at `27^(@)C` and 740 mmHg. (i) What is its volume at STP? (ii) If the same gas weighs 3-00 g, what is its molecular weight?

Explanation

To solve the given problem, we will break it down into two parts: (i) finding the volume of the gas at STP and (ii) calculating the molecular weight of the gas.

### Part (i): Finding the Volume at STP

1. **Identify the Given Values**:
- Initial Volume (V1) = 0.418 L
- Initial Temperature (T1) = 27°C = 27 + 273 = 300 K
- Initial Pressure (P1) = 740 mmHg
