Correct answer: B. Relative abundance
- A. Atomic number
- B. Relative abundance
- C. Electronic configuration
- D. F-, Ne, Na+
Explanation
A mass spectrometer is a device used to determine the mass-to-charge ratio of ions. It is commonly used to analyze isotopic composition and determine the relative abundance of different isotopes in a sample.Mass spectrometry is especially useful in determining the relative abundance of isotopes in a sample. The peaks in the mass spectrum represent different isotopes, and their heights are proportional to their abundance.This is the correct answer.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
