Moles to Volume Conversion

• a specific pressure and temperature one mole of any gas occupies the same volume.
• At 0˚c and 101.3kPa 1 mol = 22.4L
• this temperature and pressure is called STP
• 22.4L/mol is the molar volume at STP

ex. How many liters will 2.5 mol of H2 occupy at STP?

2.5 mol x 22.4L/mol= 56 L
