Molar Volume of A Gas at STP

GOOD EVENING READERS-WHO-ARE-EXTREMELY-TIRED-AND-WANT-SLEEP i curtsy in your general direction!
mother nature is an ironic vicious woman. it's a shame, she was such a nice lady before we came along

Before we begin our adventure into the land of  calculating molar volume, we must first question the blogger:

What is STP?
  • standard temperature (0°C) or (273.15 k) and pressure (1 atmosphere)
  • the standard condition to compare volume of gases
  • where one mole of gas occupies 22.4L 
What is Molar Volume?
  • the volume occupied by one mole of gas 
  • 22.4L (=22.4dm³
IN A NUTSHELL; THIS POST IS ON CONVERSION
-note: you can only convert from mole to molar volume and vice versa-

From Moles to Molar Volume
the volume occupied by 15.85 moles of N2 is 335.0L.
From Molar Volume to Moles
There are 0.379 moles contained in the sample of CO2 gas.

TA DA!
simple post wasn't it?

OH NO!
I MUST LEAVE YOU LOVELY READERS!
i must save the aussies!
