What is the correct set up to find how many liters

of Oxygen are in 41.00 g of Oxygen?

• $$\frac{41.00\ g\ O_2}{1}\times\frac{1\ mol\ O_2}{32.00\ g\ O_2}\times\frac{6.02\ x10^{23}\ L\ O_2}{1\ mol\ O_2}$$  

• $$\frac{41.00\ g\ O_2}{1}\times\frac{1\ mol\ O_2}{16.00\ g\ O_2}\times\frac{6.02\ x10^{23}\ L\ O_2}{1\ mol\ O_2}$$  

• $$\frac{41.00\ g\ O_2}{1}\times\frac{1\ mol\ O_2}{32.00\ g\ O_2}\times\frac{22.4\ L\ O_2}{1\ mol\ O_2}$$  

• $$\frac{41.00\ g\ O_2}{1}\times\frac{1\ mol\ O_2}{16.00\ g\ O_2}\times\frac{22.4\ L\ O_2}{1\ mol\ O_2}$$
