Question

1 micron =10^-6M . the diameter of a bacterium is approximately 0.3 microns . Express the size of the bacterium in metres ?

Answer 1

Dear Student,

$$\begin{gathered} \mathrm{As},1\mathrm{micron}={10}^{-6}\mathrm{m} \\ \Rightarrow 0.3\mathrm{micron}=0.3\times {10}^{-6}\mathrm{m}=3\times {10}^{-7}\mathrm{m} \\ \mathrm{So},\mathrm{the}\mathrm{size}\mathrm{of}\mathrm{bacterium}\mathrm{is}3\times {10}^{-7}\mathrm{m}. \end{gathered}$$
