As we know, 1 u = 1.66 x 10^-27 kg

Given,

Mass = 16.00 u

Substituting the value of mass in the relation above, we get,

$1 u = 1.66 \times 10^{-27} kg \\[0.5em] 16 u = 16 \times1.66 \times 10^{-27} kg \\[0.5em] \Rightarrow 16 u = 2.656 \times 10^{-26} kg \\[0.5em]$

Hence, the weight of oxygen atom is 2.656 x 10^-26 kg.
