Bromine has two isotopes, 79Br and 81Br. To find out the isotopic abundance of each bromine isotope, a sample of Br, was injected to a mass spectrometer which subsequently released the spectra shown below. From each spectrum height was measured and tabulated. Identify each peak in terms of formula. For example, the first peak is identified as 79Br. DATA Mass Number Peak height, cm 79 4.12 81 4.12 158 3.34 160 6.68 162 3.34 79 81 158 160 162 MASS, amu Relative Abundance
