Mass Spectroscopy Rule of 13 Example of calculating the molecular formula with carbon and hydrogen only. Mz =142 142:13 = 10.9 gives 10 carbon 10 x 13 = 130 142-130 = 12 12+10 = 22 gives 22 hydrogen C 10 H 22 Example of calculating the molecular formula with carbon, hydrogen and 1 oxygen only. Mz =142 142:13 = 10.9 gives 10 carbon 10 x 13 = 130 142-130 = 12 12+10 = 22 gives 22 hydrogen C 10 H 22 Add 1 oxygen and subtract 1 C and 4 H gives C 9 H 18 O

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
