How many moles is 32g of CH4?

How many moles of O2 would that need?

What volume would that O2 occupy?

Write the equation if complete combustion of CH4
Find the mole of CH4
Refer to the ratio of CH4 to O2 using the equation
Find the mole of O2 required accordingly
How much volume would O2 occupy? 24dm^3/mol at room temperature and pressure.

n=m/Mr
32/16=2 moles
n=cv/1000
