Check numbers by order of magnitude - Physical Chemistry

Check numbers by order of magnitude

A tight educational illustration comparing chemical extremes: a single molecule on the left labeled “~10^-23 g” and a sample jar packed with many tiny dots on the right labeled “~10^23 molecules,” with the powers of ten visually emphasized.

Chemistry has extreme numbers

Chemistry jumps between tiny things and huge counts: one molecule may weigh about $10^{-23}$ g, while one sample can contain $10^{23}$ molecules. Scientific notation keeps those numbers readable.
