Density of an object is 2.835 G cm3 if the volume is 34 cm3 what is the mass of the object density

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question we have

mass = 2.835 × 34

We have the final answer as

Hope this helps you

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!
