Question

PLS HELP The average atomic mass of carbon is 12.01 amu. Based on the atomic

masses of the two isotopes of carbon, how do the relative abundances of the
isotopes compare?

Answer 1

B. There is a very large percentage of C-12.

Step-by-step explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to realize that, since the average atomic mass is 12.01 amu, then the C-12, with an atomic mass of 12.000 am prevails over C-13 with an atomic mass of 13.003 amu as long as the average is nearer to the former.

In such a way, the answer will be B. There is a very large percentage of C-12.

Regards!
