How is isotope dilution mass spectrometry used in quantitative analysis?

In an ideal mass spectrum of a compound, the following data (intensity) is given: M* = 80% %3D M +1 = 8.8% How many carbons are expected to be present in the parent molecule? 0 7 0 8 O 10

The answer is C, how do you do it?

Determine the isotopic peak scheme for [ReCl]+ fragment in the mass spectrum?                 185Re: %37 ; 187Re: %63; 35Cl: %76; 37Cl: %24

What is responsible for the small peak at m/z = 17 in the mass spectrum of CH4?

Given C6H12O2 chemical formula. chemical shift , intergration, multiplicity and interpretation needed.

The maximum number of spectra that can be recorded per second by ToF-MS is limited by the time taken by the slowest ions to go from the source to the detector. If the slowest ion took 45.6 microsecond to travel, at what frequency could you record spectra if a new extraction cycle were begun each time this heaviest ion reached the detector? 30000 spectra/s 10000 spectra/s 11000 spectra/s 500 spectra/s 22000 spectra/s
