Molar Volume of Gas (STP)

STP, or Standard Temperature and Pressure is a set of data we use to compare our measurements to the gas' properties under the temperature of 0 degrees (273 K)

Key Formula: (one mole of gas occupies 22.4 L of gas)

1 mole of gas 
22.4L of gas

Putting it Into Use:


Calculate the volume occupied by 4.6g of C (carbon)

4.6 x 1 mole  = 0.38moles
         12.0g C

This is where the Key formula is plugged into the equation.

molar volume = 22.4 L  x 0.38moles = 6.5 L
                         1 mole

And there you go! A few easy steps.
