We are being asked to estimate the atomic mass of lead using the mass spectrum.
Recall: Mass Spectrometry allows you to determine the molecular weight of an unknown compound through its vaporization and ionization.
We are given the mass spectrum of lead with percent intensity on the vertical axis and mass (amu) on the horizontal axis.
The spectrum includes the percent intensities of four isotopes of lead:
Use the mass spectrum of lead to estimate the atomic mass of lead.
