Mass of an atom of oxygen in gram is `26.56896 xx 10^(-24)` g. What is the atomic mass of oxygen in u ?

Explanation

Mass of an atom of oxygen in gram is `26.56896 xx 10^(-24) g, and 1.66056 xx 10^(-24)g = 1u`
` therefore 26.56896 xx 10^(-24) g = ? `
= `(26.56896 xx 10^(-24)g)/(1.66056 xx 10^(-24) g//u) = 16.0 u`
Similarly mass of an atom of hydrogen = 1.0080 u
