Mr. D's Stoichiometry 3

None of the caches in this series is located at the given coordinates.

This is a series of four caches based on stoichiometry which is often used by chemists*. There are 3 caches that you will need to find by solving the associated stoichiometry problems. Clues to the location of the cache are also in the chemistry. Within containers 1, 2 and 3 is a small, brightly colored paper containing information to solve the final cache.

Tips to solving

Don't round calculations until the end
When you calculate molar masses, round all atomic masses to 2 decimal places before you add them up to find the final molar mass of the compound
When using conversions, more digits is better
assume that all reactions have a 100% yield (even though this never happens)

To find the coordinates to the third container:

About 20% of our atmosphere is O₂. Many metals oxidize in the presence of oxygen causing them to become more brittle. If that metal is used in a structure, the structure may fail.

Your north coordinates:How many grams of Iron (III) Oxide will be produced from 6.4549 L of oxygen gas (let’s keep it simple and assume the conditions are at STP)?

Your west coordinates:A major component of wood is cellulose which is a long chain of monosaccharides. What monosaccharide is used to build cellulose? This sugar is made by plants in the process of photosynthesis. If 1.2677 grams of this sugar is made by a plant, how many grams of oxygen will be given off as a byproduct?

*For you chemists: I realize that some of the reactions and calculations I have used are much more complex than presented. I have tried to keep the problems to a level that a person with general high school chemistry will be able to solve.

Congrats to [Ftc] kayes for the FTF!
