## Why does a mole of any gas occupy the same volume as a mole of any other gas?

Avogadro’s hypothesis states that equal volumes of all gases at the same temperature and pressure contain equal numbers of particles. Since the total volume that a gas occupies is made up primarily of the empty space between the particles, the actual size of the particles themselves is nearly negligible.

## Is one mole of any gas the same volume?

At standard temperature and pressure, one mole of any gas will occupy a volume of 22.4 L.

## Why does one mole of any gas always occupy the same volume 22.4 L at standard temperature and pressure?

According to my thinking, it may be due to equal diffusion of all particles when at a particular temperature and pressure. So going by this, one mole of all gases should occupy the same x L at some other temperature-pressure conditions.

## How much does 1 mole of gas weigh?

The weight of one mole of octane molecules will be equal to the summation of the weights of eight carbon atoms (at 12 grams/mole each, from carbon’s mass number) plus 18 hydrogen atoms (at 1 gram/mole each). So, doing the math (8 x 12 + 1 x 18), we see that octane weighs 114 grams/mole.

## What is Avogadro gas law formula?

Avogadro’s Law is stated mathematically as follows: Vn=k, where V is the volume of the gas, n is the number of moles of the gas, and k is a proportionality constant.

## What is the relationship between volume and pressure?

It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured.
