Here's the Problem: A compound contains only C,H, and N, It is 58.51% C and 7.37% H by mass. Helium effuses through a porous frit 3.2 times as fast as the compound does. Determinine the emperical and molecular formulas of this compound.

What I have so far:

.5851 g C = .04876 moles

.0737 g H = .0737 moles

.3412 g N = .02437 moles

emperical formula = C3H2N6

emperical mass = 122 g/mole

3.2R/R=sqrt(mm/4)

This gives me a molar mass of only 41 g/mole.

I know this can't be possible because it is less than the emperical molar mass. Can someone try to help me and see where I went wrong?
