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:
The class of this compound is <u>aldehyde or ketone (i).</u>
Explanation:
Absorption peak at 1720 cm-1 shows the presence of a carbonyl group, possibly an aldehyde or ketone with C=O bond.
Further information on molecular formula would be required for structural elucidation.
Dimensional analysis can only be used for time, distance, mass, speed, volume, and chemical quantities: False.
<h3>What is
dimensional analysis?</h3>
A dimensional analysis can be defined as an analysis of the relationships that exist between different physical quantities by identifying their fundamental (base) quantities, especially for the purpose of inferences.
Dimensional analysis is also referred to as unit-factor method or factor-label method and it is typically used to convert a different type of unit to another.
Generally, dimensional analysis can only be used for the following physical quantities:
In conclusion, a dimensional analysis cannot be used for chemical quantities such as a mole i.e it has no dimensional formula.
