Answer 1

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)`.

Step-by-step explanation:

Mass of hydrogen atom, m=
`10^(-27)` kg

Mass of bacterium , M=
`10^(-15)` kg

Mass of bacterium atom =m'

Given ;
`m' =10* m`

`m'=10* 10^(-27) kg=10^(-26) kg`

let the number of atoms in bacterium be N

`m'* N=M`

`N=(M)/(m')=(10^(-15) kg)/(10^(-27) kg)=10^(12)`

The total numbers of atom in bacterium are
`10^(12)`.
