One gram mole of a gas at NTP occupies 22.4 L. This fact is derived from

Options

A. law of gaseous volumes
B. Avogadro's hypothesis
C. Dalton's atomic theory
D. Berzelius hypothesis

Explanation

To solve the question, "One gram mole of a gas at NTP occupies 22.4 L. This fact is derived from," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Molar Volume**: At Normal Temperature and Pressure (NTP), which is defined as 0°C (273.15 K) and 1 atm pressure, one mole of an ideal gas occupies a specific volume.

2. **Recall Avogadro's Hypothesis**: Avogadro's Hypothesis states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This implies that the volume occupied by one mole of any gas is the same under the same conditions of temperature and pressure.
