David L. . Baumer. , NC State University. Academy of Legal Scholars in Business, August 2010 Annual Conference. Empirical Research. Although not all legal scholarship requires empirical research, clearly in some instances, empirical research enhances the credibility of contentions made in scholarly legal writings. You should know this for the quiz!. Empirical and Molecular Formulae. Empirical Formula. If needed, change % to g.. Do . a molar conversion to change from . g. mol.
