...Moles to Volume conversion

Today we learned how to convert a mole of any gas into volume.

One mole of any gas at a specific pressure and temperature will always occupy the same volume.                  
-at 0 °C and 101.3 k Pa 1mol = 22.4L
-22.4L/mol is the molar volume at STP
(This temperature and pressure is called STP)

example:
-how many liters will 3.5mol of N occupy at STP (standard temperature and pressure)?
3.5mol x 22.4L = 78L
              1 mol
-at STP an unknown gas is found to occupy 367ml. How many moles of gas must there be?
*When doing a question like this be careful and notice that it is measured in mL instead of liters
367mL x    1L     = 0.367L
             1000mL
*first convert 367mL into liters (0.367L)
 0.367L x 1mol  = 0.0164mol
                22.4L
*now simply do the work.
