A 0.325-g sample of dark red crystalline compound dissolves in 12.2 g ethylene dibromide, giving a solution

Question:

A 0.325-g sample of dark red crystalline compound dissolves in 12.2 g ethylene dibromide, giving a solution that freezes at 7.97 °C. Ethylene dibromide has a normal freezing point of 9.80 °C and a freezing-point depression constant of 11.8 °C/m.

(a) What is the molar mass of the red solid?

(b) The compound is 32.5% iron by mass. Calculate the number of iron atoms in each molecule of this solute.
