Metallic iron crystallizes in a cubic lattice. The unit cell edge length is \(287 \mathrm{pm}\). The density of iron is \(7.87 \mathrm{~g} / \mathrm{cm}^{3}\). How many iron atoms are there within a unit cell?
What is the equilibrium vapor pressure of a liquid? How does it change with temperature?
A \(1.20-\mathrm{g}\) sample of water is injected into an evacuated \(5.00-\mathrm{L}\) flask at \(65^{\circ} \mathrm{C}\). What percentage of the water will be vapor when the system reaches equi librium? Assume ideal behavior of water vapor an that the volume of liquid water is negligible. The va por pressure of water at \(65^{\circ} \mathrm{C}\) is \(187.5 \mathrm{mmHg}\).
