Final answer:

The compound's empirical formula is C5H7N, and its empirical formula mass is 81.13 g/mol formula unit.

Step-by-step explanation:

The compound's empirical formula can be determined by finding the molar ratios of each element in the sample. In this case, the molar ratio of carbon to nitrogen (C:N) and hydrogen to nitrogen (H:N) are adequately close to whole numbers. Therefore, the empirical formula is C5H7N. The empirical formula mass of the compound is 81.13 g/mol formula unit.
