a.

b.
c.
d.

e.

Answer : The volume occupied by lead is, 2.20 mL

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used for density :

Given :

Mass of an lead = 25.0 grams

Density of lead = 11.34 g/mL

Now put all the given values in the above formula, we get the volume of lead.

Therefore, the volume occupied by lead is, 2.20 mL

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
