Question

The diameter of an atom is approximately 1 × 10-10 m. What is the diameter in picometers?

Answer 1

Answer : The diameter in picometer is,
`1* 10^(2)pm`

Explanation :

As we are given that the diameter of an atom is
`1* 10^(-10)m`. Now we have to convert it into picometers.

Conversion used from meter to picometer is:

`1m=1* 10^(12)pm`

As,
`1m=1* 10^(12)pm`

So,
`1* 10^(-10)m=(1* 10^(-10)m)/(1m)* 1* 10^(12)pm`

`1* 10^(-10)m=1* 10^(2)pm`

Thus, the diameter in picometer is,
`1* 10^(2)pm`
