(1) A sample of the oxide of magnesium weighing 10.000 g contains 6.031g of Mg.
(a) Use the data to determine the empirical formula for the oxide of magnesium.

(2) A student used the procedure described in this module to determine the empirical formula of an oxide of titanium (Ti). A crucible cover was heated to a constant mass of 34.749 g. The mass of the crucible, crucible cover, and sample of Ti was 36.383 g. Following the reaction of the Ti metal with O2, the crucible, crucible cover, and contents were heated to a constant mass of 37.472 g.
(a) Determine the mass of the oxide of Ti.
(b) Determine the mass of Ti in the compound.
(c) Determine the mass of O in the compound.
(d) Calculate the number of moles of Ti in the compound, using equation a.
(e) Calculate the number of moles of O in the compound, using equation a.
