In 1774 Joseph Priestly conducted one of his most famous experiments which
lead to a method for the preparation of oxygen. The experiment involved heating
a sample of mercury II oxide with a large lens.

The equation for this reaction is shown below:


2HgO(s) = 2Hg(l) + O2(g)

a) What volume of O2(g) would be obtained if 1.08g of mercury
II oxide were completely decomposed? (Given that 1 mole of a gas occupies 24
dm3 under the experimental conditions)
