Transcribed Image Text:

An unknown has a molar mass (M) of 134 g/mol. In a mass spectrometer, the following information is seen: Mass of peak 134 135 136 Intensity of peak c. What is the atomic symbol for this atom? 47.0% 3.2% 15.3% a. Determine the adjusted intensities of the peaks at 135 and 136. And put them in the table. b. This molecule has an atom other than C, H, N and O. How does the data tell you that this is the case? d. What are the masses of the two isotopes for this atom? e. Which isotope of that atom is present in the 134 g/mol molecules? f. What is the mass of the C, H, N and O part of the molecule? Adjusted peak intensity h. Does the molecule have an even or odd number of nitrogen atoms? 100% g. How many carbon atoms are estimated to be in this molecule? How did you determine this? j. How many elements of unsaturation are there in this molecule? i. Using this information, what is the formula for this molecule? (e.g. C4HSON) I'm not asking for the structure.
