Mathematics of Chemistry


Because atoms are so tiny, there's a whole set of math terms set up so we can measure these elements. But don't panic—even though it may seem like a completely different language, it's not all that distinct from your everyday math.

The most important equation to be familiar with is Avagradro's number—6.02 x 1023. This number makes up a mole of any given atom. Why use this multiplier? Simply because atoms are so small that we need a common equation that will allow us to measure them in a meaningful way. All particles, multiplied by Avagradro's number, will occupy 22.4L of ideal gas volume at Standard Temperature and Pressure.

From this mole concept, we get a particular "atomic math", stoichiometry—the study of quantitative relationships implied by chemical equations. Pretty much, stoichiometry solves chemical problems and relationships through math, and especially uses the mole concept that we described above.
