Assuming the peaks are caused by 12 and 13C isotopes, determine the number of carbon atoms in the compound. Natural abundances: 12 is 98.93% and 13 is 1.07% Number 2 carbon atoms A Previous 3 Give Up & View Solution Check Answer Next Exit 8 Hint

Explanation / Answer

Number of carbon atoms = ( M+ 1/ M) x 100 = (3.603 / 41.64) x 100 = 8
