Practice Problem: Empirical and Molecular Formulas

The video tutorial explains how to determine the molecular formula of nicotine using given mass percentages and molar mass. It starts with converting mass percentages to grams, then to moles, and uses these to find the empirical formula. Finally, it calculates the molecular formula by comparing the empirical formula mass to the given molar mass.

Explain the process of converting mass percentages to moles for the elements in nicotine.
