Astudent measures the mass of a metal bar as 57.21 g. the student fills a graduated cylinder with water and determines the volume of water to be 53.70 ml. the student places the metal bar into the graduated cylinder and records the new volume as 58.80 ml. calculate the density of the metal bar and identify it from the choices that appear in table 1.1.

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
