Question

How would you determine the number of Atoms per molecule and determine the sulfur allotrope based on the

information below?

Molecular Weight Determination by freezing point depression:

Mass of Naphthalene: 20.131 g

Freezing Point of Naphthalene: 80 degrees C

Mass of Sulfur: 2.016

Freezing point of Naphthalene-Sulfur solution: 76.95

Freezing point depression to constant for naphthalene: 6.8 C/molal.

Determine the number of Atoms per molecule AND determine the sulfur allotrope
