NOTE: Stoichiometry 2 was archived since it is in the new park. As soon as the park is complete a new location will be set. If you need the info, contact me.

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 first container:
The grass is so green here in the summer! This is due in part to the large amount of nitrogen based fertilizers applied to the grass by the landscaping technicians. Plants need nitrogen for building proteins, but they can’t use the abundant N2 gas from the atmosphere. One way to make useable nitrogen for plants is through the Haber Process.
Your north coordinates: How many grams of hydrogen will be needed to make 0.3820 pounds of ammonia? (use 3 decimal places for pounds to grams conversion)
N 40 your answer in minutes
Your west coordinates: The Haber process requires large amounts of hydrogen gas. One source of this gas is the hydrolysis of water. How many L of water would need to be hydrolysed to produce 46.30 g of hydrogen? (density of water is 1 g/mL)
W 105 your answer in minutes

*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.
