3. A student performed an experiment similar to the one in this module to determine the empirical
formula of a compound containing chromium (Cr) and O. After heating 0.4550 g of pure Cr wire in an
excess of air, the sample was cooled and weighed. The mass of the compound formed was 0.8749 g.
The molar masses of Cr and O are 52.00 g mol- and 16.00 g mol-, respectively.
