Question

Wood floats in water, 1 gram is defined as the mass of 1 cubic centimeter of water, a cubic centimeter of quartz weighs ~2.65 g and a cubic centimeter of galena weighs about 7.5 g. the density of these materials from highest to lowest is ________.

Answer 1

First, let us calculate the density of all materials in gram per cubic centimetre (g / cm^3).

Wood = 1 g / cm^3

Quartz = 2.65 g / cm^3

Galena = 7.5 g / cm^3

So arranging the density from highest to lowest:

Galena, Quartz, Wood
