Iron has a density of 7.86 g/cm^3. calculate the volume of a piece of iron having a mass of 3.99 kg.

508 cm^3

Explanation:

3.99 kg * (1000 g)/(1 kg) = 3990 g

density = mass/volume

density * volume = mass

volume = mass/density

volume = (3990 g)/(7.86 g/cm^3)

volume = 508 cm^3

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
