Question

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? Check all that apply. Check all that apply.

15.2 g copper and 50.0 g copper

11.2 g gold and 14.9 g gold

20.2 g silver and 20.2 g copper

15.4 g gold and 18.7 g silver

Explanation / Answer

answer : 20.2 g silver and 20.2 g copper

explanation:

density = mass / volume

volume is already fixed . so density depends on mass of metal . here both metals have same mass . so same density
