Question

How many molecules are in 22.41 L of an ideal gas at STP?

Answer 1

There has been an universal standard of volumetric calculations of ideal gases that has been set up.

Explanation:

According to certain rules of Avogadro,

"`color(red)(22.41 Litres)` of any ideal gas at STP contains `color(blue)(6.023xx10^(23)` molecules and is equal to `color(orange)(1 mol)` of the gas."

So, `color(red)(22.41 Litres)` of the ideal gas at STP contains `color(blue)(6.023xx10^(23))` molecules.

Hope it Helps :)
