Ipatiy [6.2K]

Answer:

The new atomic mass of oxygen is 64u

Explanation:

Given

Taking the mass by part on the scale of 1/12 gives atomic mass of oxygen = 16 u

Now, when the scale is changed from 1/12 to 1/3, the new mass would become

\frac{16}{\frac{1}{12} } * \frac{1}{3} \\= \frac{16 * 12}{3} \\= 64

The new atomic mass of oxygen is 64u
