Mercury(II) oxide, a red powder, can be decomposed by heating to pro-
duce liquid mercury and oxygen gas. When a sample of this compound is de-
composed, 3.87 g of oxygen and 48.43 g of mercury are produced. In a second
experiment, 15.68 g of mercury is allowed to react with an excess of oxygen
and 16.93 g of red mercury(II) oxide is produced. Show that these results are
consistent with the law of constant composition.
