10¹¹ is the approximate number of atoms in a bacterium.
<h3>
What do you understand by mass of element?</h3>
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu).
Given,
Mass of a bacterium atom = 10⁻¹⁵ kg.
Mass of a hydrogen atom = 10⁻²⁷ kg.
From the above observation ,
The average mass of an atom of the bacterium is ten times the mass of a hydrogen atom.
Atomic mass 1 bacterium atom = 10 x mass of hydrogen atom
= 10 x 10⁻²⁷ kg.
= 10⁻²⁶ kg.
Thus,
The number of atoms in a bacterium
= ![\frac{Total mass}{Atomicmass of 1 bacterium}](https://tex.z-dn.net/?f=%5Cfrac%7BTotal%20mass%7D%7BAtomicmass%20of%201%20bacterium%7D)
= ![\frac{10^{-15} }{10^{-26} }](https://tex.z-dn.net/?f=%5Cfrac%7B10%5E%7B-15%7D%20%7D%7B10%5E%7B-26%7D%20%7D)
= ![10^{11}](https://tex.z-dn.net/?f=10%5E%7B11%7D)
