Question

Diff between relative aand percent abundance

A) Relative abundance is expressed as a fraction, while percent abundance is expressed as a percentage.
B) Relative abundance is a measure of the frequency of a particular isotope compared to all isotopes, while percent abundance is the proportion of a specific isotope expressed as a percentage of the total.
C) Relative abundance is always given in parts per million (ppm), while percent abundance is given in parts per hundred (pph).
D) There is no significant difference between relative abundance and percent abundance.

Answer 1

Relative abundance is expressed as a fraction and represents the frequency of a specific isotope compared to all isotopes, while percent abundance is expressed as a percentage and represents the proportion of a specific isotope out of the total.

Step-by-step explanation:

The main difference between relative abundance and percent abundance is the way they are expressed. Relative abundance is expressed as a fraction, while percent abundance is expressed as a percentage. For example, if the relative abundance of a particular isotope is 0.6, then the percent abundance would be 60%.

Another difference is the concept they represent. Relative abundance is a measure of the frequency of a particular isotope compared to all isotopes, while percent abundance represents the proportion of a specific isotope expressed as a percentage of the total.

Lastly, relative abundance can be given in different units such as parts per million (ppm), while percent abundance is always given in parts per hundred (pph).
