The concentration of pure osmium tetroxide (molar mass = 254.23 g/mol) is c(OsO 4) = 5.1 kg/L / 254.23 g/mol = 20.1 mol/L. A typical protein in bacteria, such as E. coli, may have about 60 copies, and the volume of a bacterium is about 10 −15 L. Thus, the number concentration C is C = 60 / (10 −15 L) = 6 × 10 16 L −1. The molar ...

The total dependency ratio is the total numbers of the children (ages 0–14) and elderly (ages 65+) populations per 100 people of adults (ages 15–64). A high total dependency ratio indicates that the adult population and the overall economy face a greater burden to support and provide social services for youth and elderly persons, who are often economically dependent.
