Molar Volume at STP

                                    Today in Class we leart about molar volume. 


What is molar volume?
molar volume is  gas at Standard Temperature and Pressure(STP) is 22.414 L/mol.


Ex: Find the Volume occupied by 3.00 mol of NO2 at STP
Ans: 3.00 NO2*22.4L/1mol =67.2L of NO2




LOOK IS A MOLE BALL IN STP!!!!

 

This is How to Convert From Moles to STP and from STP to Moles!!!

Ex: find the number of moles in 187.04L of nitrogen gas(N2) at 0 degrees and 101.3kPa


Ans:187.04L N2*1mol/22.4L=8.35 mol N2
 (The L cancels and you get Mol!!!)
