Introduction to Stoichiometry

Avogadro's number  -  6.02×10²³ ; the number of particles that make up the measure of 1 mole.

Chemically engineered  -  Produced by chemical means.

Mole  -  A measure of amount. 1 mole equals 6.02×10²³ items of something. The number is so massive because moles are used to measure the amount of molecules, atoms, and other incredibly miniscule particles.

Stoichiometry  -  The calculation of quantities in chemical equations.
