Natali5045456 [20]

The question is incomplete, the complete question is :

Calculate the approximate number of atoms in a bacterium. Assume the average mass of an atom in the bacterium is 10 times the mass of a hydrogen atom.(Hint the mass of hydrogen atom is on order of 10^{-27} kg and the mass of bacterium is on order of 10^{-15} kg

Answer:

The total numbers of atom in bacterium are 10^{12}.

Explanation:

Mass of hydrogen atom, m= 10^{-27} kg

Mass of bacterium , M= 10^{-15} kg

Mass of bacterium atom =m'

Given ; m' =10\times m

m'=10\times 10^{-27} kg=10^{-26} kg

let the number of atoms in bacterium be N

m'\times N=M

N=\frac{M}{m'}=\frac{10^{-15} kg}{10^{-27} kg}=10^{12}

The total numbers of atom in bacterium are 10^{12}.
