Problem 11
At an altitude of \(40 \mathrm{~km}\) above the earth's surface, the atmospheric pressure is 5.00 torr, and the surrounding temperature is \(-20^{\circ} \mathrm{C}\). If a weather balloon is filled with \(1.000 \mathrm{~mol}\) of He at 760 torr and \(22^{\circ} \mathrm{C}\), what is its a) initial volume before ascent? b) final volume when it reaches \(40 \mathrm{~km}\) in altitude? (Assume the pressure of the gas equals the surrounding pressure.)
Problem 11
Oxygen is a product of the decomposition of mercury(II) oxide: $$ 2 \mathrm{HgO}(\mathrm{s}) \rightarrow 2 \mathrm{Hg}(\ell)+\mathrm{O}_{2}(\mathrm{~g}) $$ What volume of \(\mathrm{O}_{2}\) is formed from the decomposition of \(3.009 \mathrm{~g}\) of \(\mathrm{HgO}\) if the gas has a pressure of 744 torr and a temperature of \(122^{\circ} \mathrm{C}\) ?
