What is the mass (g) of a 17.4 mL piece of material, if the density is 3.4 g/mL?

59.16 g

Explanation:

Mass = Density × Volume

= 3.4 g/mL × 17.4 mL

= 59.16 g or

59.2 g (rounded to three significant figures) or

59 g (rounded to two significant figures)

Hope that helps.

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.
