AP CHEMISTRYMass Spectrometry
Analyze mass spectra to determine isotopic composition and calculate average atomic mass. Visualize how mass spectrometry ionizes atoms, separates ions by mass-to-charge ratio (m/z), and detects relative abundances. Practice interpreting mass spectrum peaks to identify isotopes, calculate weighted average atomic mass using (mass × abundance) for each isotope, and understand applications in identifying unknown compounds and determining molecular formulas.
