Amothball, composed of naphthalene (c10h8), has a mass of 1.72 g .how many naphthalene molecules does it contain?

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

1 mole of napthalene contains = molecules

Thus 0.0134 moles of napthalene contain= molecules

Thus there are napthalene molecules.
