The specific gravity of iron is 7.87, and the density of water at 4.00 ∘c is 1.00 g/cm3. you can use this information to find the density of iron. find the volume occupied by 4.50 g of iron.

The volume of iron occupied is

Explanation:

The relationship between specific gravity and density of a substance is given as:

Specific gravity of iron = 7.87

Density of water =

Putting values in above equation we get:

To calculate volume of a substance, we use the equation:

Density of iron =

Mass of iron = 4.50 g

Putting values in above equation, we get:

Hence, the volume of iron occupied is

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
