Mass Spectrometry Analysis of Combustion Reactions-Sp04 1) A hydrocarbon is combusted in oxygen to give products. Analysis of the products gives the mass spectrum below. What is the empirical formula of the compound? If the molar mass of the compound is 30g/mol, what is the molecular formula of the compound? Write a balanced chemical equation for the combustion of this molecule in air. 2) A hydrocarbon is combusted in oxygen to give products. Analysis of the products gives the mass spectrum below. What is the empirical formula of the compound? If the molar mass of the compound is 42g/mol, what is the molecular formula of the compound? Write a balanced chemical equation for the combustion of this molecule in air. 18 44 18 44
