Answer:

You can find the empirical formula given these data. YOU CANNOT FIND THE molecular formula.

Explanation:

In #100# #g# of stuff, there are #(44.44*g*C)/(12.011*g*mol^-1) = 3.66*mol#, and #(3.73*g*H)/(1.00794*g*mol^-1) = 3.71*mol#, and #(51.83*g*N)/(14.01*g*mol^-1) = 3.70*mol#.

Thus the empirical formula is #CHN#. The molecular formula is some multiple of #CHN#, but we don't know what it is on the basis of these data.
