Remember this template C H Mass in grams 85.72 14.28 Moles 85.72/12 14.28/1 Ratio 7.14 14.28 Simple ratio 1 2 Empirical formula CH 2

What to do if you have horrible numbers ,[object Object],[object Object]

This looks pretty Complicated so let us just Consider Room Temperature and Pressure, then 1mole Of any gas occupies 24 liters =24,000cm 3 You can thank Mr Avogadro for this

Let us now consider chemical equations
