Two well-known organic chemicals are benzene , and propane, Benzene has a molecular weight of 78.11 g/mol and propane 44.096 g/mol, where the molecular weight is a useful measure in chemistry and is defined as the mass of 1 mole (Avogadro’s number) of molecules or atoms. Determine the molecular weight (in g/mol) of pure hydrogen and pure carbon. Hint: The subscripts in the molecular formula are the number of atoms of that type per molecule. Set up two simultaneous equations to solve for the molecular weights.
