Question

atomic mass of oxygen according to conventional scale is 16u. if we change the scale from 1/12 to 1/3 then its atomic mass will be

Answer 1

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
