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".

You are trying to synthesize a new compound that has potential anti-HIV activity – it could be the next drug used to treat HIV! It can be synthesized (made) from two commercially available starting molecules – call them “A” and “B”. They can be combined according to the following equation:A + 2B -> desired drug molecule. “A” has a molar mass of 85.0 g/mol, and “B” has a molar mass of 130.0 g/mol. You look these starting materials up in a chemical catalog, and here’s what you find:compound “A” costs $5000.00 per 5.0 gramscompound “B” costs $2500.00 per 1.0 gram(though you can buy either in any amount)a) You currently have $10000.00 to spend on starting materials.
