How would you sketch the mass spectrum of gallium given its two naturally occurring isotopes with the following masses and natural abundances: Isotope Mass (amu) Abundance (%) Ga-69 68.92558 60.108 Ga-71 70.92470 39.892?

Verified step by step guidance

1. <Determine the relative abundance of each isotope by converting the percentage to a decimal. For Ga-69, it is 0.60108 and for Ga-71, it is 0.39892.>
2. <Consider the x-axis of the mass spectrum, which represents the mass-to-charge ratio (m/z). Since the charge is typically +1 for singly charged ions, the m/z values will be approximately equal to the isotopic masses: 68.92558 for Ga-69 and 70.92470 for Ga-71.>
3. <The y-axis of the mass spectrum represents the relative intensity, which is proportional to the abundance of each isotope.>
4. <Plot the first peak at m/z = 68.92558 with a relative intensity corresponding to the abundance of Ga-69 (60.108%).>
5. <Plot the second peak at m/z = 70.92470 with a relative intensity corresponding to the abundance of Ga-71 (39.892%).>
