The density of carbon in the form of diamond is 3.51 g/cm^3. if you have a small diamond with a volume of 0.0270 cm3 what is its mass in grams

Explanation:

It is known that density is mass divided by volume in liter.

Mathematically,    Density =

It is given that density is 3.51 and volume is 0.0270 .

Therefore, calculate the mass as follows.

                    Density =

               3.51 =

                         mass = 0.09477 g

Thus, we can conclude that mass of given substance is 0.09477 g.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
