## What gas occupies 22.4 at STP?

A mole of any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm). Figure below illustrates how molar volume can be seen when comparing different gases. Samples of **helium** (He), nitrogen (N_{2}), and methane (CH_{4}) are at STP.

## Why does 1 mole of any gas occupy the same volume?

So the volumes have equal moles of separate particles (molecules or individual atoms) in them. Therefore one mole of any gas (formula mass in g), at **the same temperature and pressure** occupies the same volume .

## What will be the volume occupied by 1 mole of A?

Hence, We can see that the molar volume of a gas at S T P is 22.4 litres. Therefore, it is proved that one mole of a gas occupies **$22.4L$ of the** volume at STP.

## What is P1 V1 P2 V2?

The relationship for Boyle’s Law can be expressed as follows: **P1V1 = P2V2**, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.
