Mass Spect: Isotopes

Problem: Propose the number of carbons for a compound that exhibits the following peak in its mass spectrum: 

(M)+• at m/z = 72, relative height = 38.3% of base peak

(M+1)+• at m/z = 73, relative height = 1.7% of base peak 

5m

Problem: Predict the approximate height of the (M + 1) peak for the molecule icosane, molecular formula C20H42.
