Question

The mass of an atom of an oxygen is 8 amu. Express it in kg​

Answer 1

Mass of one atom of oxygen – 16.0 u

1 u = 1.66 * 10^-27

The mass of an atom of oxygen = 16.0 * 1.66 * 10^-27 kg

= 2.656 * 10^-26 kg

Answer 2

$\Large\mathtt\green{ }\huge\underline\mathtt\red{Answer : }$

Given,

Mass of one atom of oxygen 16.0 u

1u= 1.66 × 10-27

The mass of an atom of oxygen = 16.0 1.66 × 10^-27 kg

= 2.656

10-26 kg
