Asked by Kiana

Mothballs are composed of a chemical called naphthalene which has a formula of C10H8
a) what is the mass of a single naphthalene molecule in amu?
b) what is the molar mass of naphthalene?
c) what is the mass of a single naphthalene molecule in grams?

I think I got b: 128.16 g/mol but the other ones I have no idea. If I had to guess I would say they all have the same answer.

b is correct.
a. A single molecule has a mass of 128.15 amu
c. Since there are 6.022E23 molecules in a mole (128.16g), then 1 atom has a mass of 128.16/6.022E23 = ?
