Copper has a density 0f 8.96 g/cm3. Determine the volume of a piece of copper with mass of 10.56 g.
(this is what I need the answer to) If the piece of copper is a wire with a length of 125.5 cm, what is its diameter?
This is all the information I received.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
