Finding the Formula of a Metal Oxide through Experimentation

The video tutorial explains how to determine the formula of a metal oxide using experimental methods. It focuses on the oxidation of magnesium, detailing the process of weighing magnesium, heating it in a crucible, and calculating the resulting magnesium oxide's mass. The tutorial demonstrates how to calculate the empirical formula by converting masses to moles and determining the ratio of magnesium to oxygen. The empirical formula of magnesium oxide is found to be MgO, and the video concludes with a summary of the steps involved in the experiment.
