Question

A cell division is 80 Angstrom (A) thick. If an angstrom unit is   10^-10 m, what is the thickness of the cell division in  a) micrometer     b) meter and c) picometer.

Answer 1

$$d=80\cdot10^{-10}(10^{6})=8\cdot10^{-3}\mu m\\ d=80\cdot10^{-10}=8\cdot10^{-9}\ m\\ d=80\cdot10^{-10}(10^{12})=8\cdot10^{3}\ p m$$
