WebIt's because of something called binding energy. Carbon-12 has a mass of 12 amu by definition. Theoretically, this would mean that each proton and each neutron has a mass of one amu, but this turns out not to be so. The actual mass of a proton is about 1.007 amu, and the mass of a neutron is about 1.008 amu. WebApr 9, 2024 · Solution: From the given molecular formula it is clear that the given chemical substance has 6 carbons and 6 hydrogen atoms. Now, the atomic weights of carbon and hydrogen atoms are 12.0107 amu and 1.008 amu respectively. Thus, the molecular weight of C6H6 is = 6* (atomic weight of carbon) + 6* (atomic weight of hydrogen) = 78.112 amu.
