Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, find its volume, and calculate its density. 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
a) 11.2 g gold and 14.9 g gold
b) 20.2 g silver and 20.2 g copper
c) 15.4 g gold and 18.7 g silver
d) 15.2 g copper and 50.0 g copper
