1.) The volume of an irregularly shaped solid can be determined by immersing the solid in a liquid and measuring the volume of liquid displaced. A sample of lead shot weighs 155 g. It is then placed into a graduated cylinder that contains some water. The lead shot does not float. The water in the cylinder was at a level of 14.3 mL before the lead shot was added and at 28.0 mL afterward. Find the volume and density of the sample of lead shot.

2.) Ethylene glycol, C2H6O2, is an ingredient of automobile antifreeze. Its density is 1.11 at 20C. If you need 130. of this liquid, what mass of the compound, in grams, is required?
