Liters to Moles Calculator

Formula

The formula to convert Liters to Moles (n) for an ideal gas at STP is:

$n = \frac{V}{VM}$

Where:

$n$ is the Number of Moles (mol)
$V$ is the Volume of the Gas (liters)
$VM$ is the Molar Volume of an Ideal Gas at STP (22.414 liters/mol)

What is the Molar Volume?

The molar volume is the volume occupied by one mole of an ideal gas at standard temperature and pressure (STP), which is defined as 0 degrees Celsius and 1 atmosphere of pressure. The molar volume of an ideal gas at STP is 22.414 liters per mole. This value allows you to convert between the volume of a gas and the amount of substance in moles under these standard conditions.

Example Calculation

Let's consider an example:

Volume of Gas (V): 44.828 liters
Molar Volume (VM): 22.414 liters/mol

Using the formula to calculate the number of moles:

$n = \frac{44.828}{22.414} \approx 2.0 \, \text{mol}$

This means that 44.828 liters of gas at STP is equivalent to approximately 2.0 moles.
