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

Nov 10, 2016

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

#### Explanation:

According to certain rules of Avogadro,

"$\textcolor{red}{22.41 L i t r e s}$ of any ideal gas at STP contains color(blue)(6.023xx10^(23) molecules and is equal to $\textcolor{\mathmr{and} a n \ge}{1 m o l}$ of the gas."

So, $\textcolor{red}{22.41 L i t r e s}$ of the ideal gas at STP contains $\textcolor{b l u e}{6.023 \times {10}^{23}}$ molecules.

Hope it Helps :)
