Question

The radius of hydrogen atom is 0.53x10
-10 m. Convert it in cm, mm, nm respectively?

Answer 1

Given that,

Radius of hydrogen atom is

$r=0.53\times10^{-10}\ m$

We know that,

Conversion in meter,

$1\ Angstrom =10^{-10}\ m$

$1\ cm=10^{-2}\ m$

$1\ mm=10^{-3}\ m$

$1\ nm=10^{-9}\ m$

We need to calculate the radius in cm, mm and nm

Using conversion method

Radius in cm

$r=0.53\times10^{-10}\times100$

$r=0.53\times10^{-8}\ cm$

Radius in mm,

$r=0.53\times10^{-10}\times1000$

$r=0.53\times10^{-7}\ mm$

Radius in nm,

$r=0.53\times10^{-10}\times10^{9}$

$r=0.53\times10^{-1}\ nm$

$r=0.053\ nm$

Hence, (a). Radius of hydrogen atom is $0.53\times10^{-8}\ cm$

(b). Radius of hydrogen atom is $0.53\times10^{-7}\ mm$

(c). Radius of hydrogen atom is 0.053 nm.
