There is not enough information to determine anything about the relative abundances of the two isotopes.
<h3>What are isotopes?</h3>
Isotopes are atoms that have the same atomic number but different mass numbers. We know that all the isotopes of an element are not available to the same extent in nature.
Hence, from the average atomic mass of carbon, we can see that there is not enough information to determine anything about the relative abundances of the two isotopes.

Answer:
Dalton says atoms of a given element are identical in mass and the modern one says atoms of a given element are identical in average mass. ... Modern theory says they atoms can be subdivided, created or destroyed by ordinay means.

<span>Greenhouse gases are so difficult to measure, because carbone dioxide, m</span>ethane, chlorofluorocarbons comes from multiple sources, some of which are relatively hard to measure.
For example, missions related to wetlands, deforestation, cattle, leakage from natural gas wells, storage facilities and distribution systems and because such leaks are highly variable and depend on factors such as well construction methods and maintenance systems for infrastructure.
