Full Answer

The formula for naphthalene, C10H8, can be used to find the molar mass, as it shows the number of atoms of each element that a molecule of naphthalene contains. Using the periodic table of elements, an atom of carbon has a mass of about 12.0096 grams per mole, while an atom of hydrogen has a mass of about 1.007 grams per mole. The formula for the molar mass is thus 12.0096(10) + 1.007(8), which is equal to about 128.17 grams per mole. The value may vary slightly depending on rounding choices.
