The density of a substance is equal to the ratio of mass of substance to the volume. The formula for density is;
Density = mass / volume
Density = 3.12 g/ cm3
mass = 28.1 grams
Volume = mass / density
Volume = 28.1 grams / 3.12 grams / cm3
Volume = 9 centimeter cube
So, the volume of the bromine is 9 centimeter cube.
Density = mass / volume
Density = 3.12 g/ cm3
mass = 28.1 grams
Volume = mass / density
Volume = 28.1 grams / 3.12 grams / cm3
Volume = 9 centimeter cube
So, the volume of the bromine is 9 centimeter cube.
