The Greek mathematician Archimedes is credited with discovering how to verify the amount of pure gold in an irregularly shaped object (e.g., a crown) by placing it in water. How much water should be displaced by a pure gold object having a mass of 1.45 kg?
Starting from the ideal gas equation, show how you can calculate the molar mass of a gas from knowledge of its density.
Assume that a student places 1.0 mol of solid PbI2 in 1.0 L of water. Part of the lead iodide dissolves according to the following reaction PbI2(s) Pb2+ (aq) + 2I-(aq) After allowing the solution to sit for 30 minutes the student determines that th..
