Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

If you purchase 1 bottle of 120 tablets of 650. mg sodium bicarbonate in the pharmacy aisle (the cheapest I found was $4.99), you are paying a significant amount of money for the bottling, capsuling and mark-up. You can purchase for $28.99 at www.amazon.com 30.0 pounds of sodium bicarbonate. How many bottles of tablets can you make out of the 30.0 lbs of NaHCO3 if you already have the capsules, labeling and bottles? If you are able to sell each bottle for $4.99 , once subtracting the $28.99 for the cost of the sodium bicarb, what is the gross profit before other bills?
