Mr. D's Stoichiometry 2
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 second container:
Acid rain is caused by emissions from cars and factories, as well as natural sources such as volcanic eruptions. It can be destructive to certain building materials such as aluminium.
Your north coordinates: Sulfuric acid, a major component of acid rain, is not formed directly from cars and factories. There are several reactions that happen in the atmosphere between sulfur dioxide, sulfur trioxide, water and other compounds. Sulfur trioxide can combine with water to form sulfuric acid. How many grams of sulfuric acid would be formed from 5.6368 mL of water. (the density of water is 1 gram/mL)

Your west coordinates: Certain metals react with acids to form hydrogen gas and salts of that metal. When sulfuric acid and aluminium combine, hydrogen gas and aluminium sulfate form. How many grams of sulfuric acid will need to fall on the aluminium to consume 140.11 milligrams of Al?

Please return the container exactly as you found it!!
*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.
