THE CHALLENGE

You are hired as the laboratory manager at a major pharmaceutical company. Your first task is to purchase chemicals for the aspirin production line in order to produce 125,000 aspirin bottles per day.

GENERATE IDEAS


 * How much aspirin is in each bottle?


 * What is the total amount of aspirin needed to be produced?


 * What chemicals are used in the production of aspirin?


 * Is any product lost in the production line?

MULTIPLE PERSPECTIVES

Provided by professor at the end of the Generate ideas portion. (You tube presentation, research articles, etc.)

RESEARCH & REVISE


 * Examine typical aspirin daily production


 * Examining typical production line % loss


 * Examine reactions for aspirin production


 * Balancing chemical equations


 * Computing moles of B from mass of B


 * Converting moles of B to moles of A


 * Examine unit conversion factors

 * Homework and exam problems that apply the module concepts to unrelated applications
 * Examples:
 * An automobile engine produces energy by the combustion of gasoline, which is primarily octane, C8H18. Being a concerned citizen for your local carbon footprint you decide to compute the amount of carbon dioxide that is emitted from your car in one year.
 * The compound diborane (B2H6) was at one time considered for use as a rocket fuel. As an engineer you need to know how many grams of liquid oxygen would a rocket have to carry to burn 10 kg of diborane completely?
