The correct order of unit conversions for gram to gram stoichiometry is

• mol -> mol -> g

• g -> mol -> mol -> g

• mol -> g -> mol -> g

• mol -> g -> g -> mol

If we have 10 g of O₂, how many grams of H₂O can we make? Place the parts of the setup of a gram to gram conversion in the correct position.
