The formula to convert Liters to Moles (n) for an ideal gas at STP is:
\[ n = \frac{V}{VM} \]
Where:
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.
Let's consider an example:
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.
