Mercury has a density of 13.6 g/cm³. Which of these materials will float in mercury? Check all that apply. iron, density: 7.8 g/cm³
aluminum, density: 2.7 g/cm³
silver, density: 10.5 g/cm³
gold, density: 19.3 g/cm³
uranium, density: 18.7 g/cm³
lead, density: 11.3 g/cm³

iron, density: 7.8 g/cm³

aluminum, density: 2.7 g/cm³

silver, density: 10.5 g/cm³

lead, density: 11.3 g/cm³

Explanation:

me objects that sink in water will float on mercury, including pieces of lead, silver and steel. However, pieces of gold sink, since gold has a higher density then mercury does.

enser items will sink on a media, but less dense will float. It is denser than iron, copper, lead, brass, nickel, silver, aluminum, tin, and concrete. That means that solid chunks of all those materials will float on mercury which is liquid at room temperatures
