What is the density of an object with a mass of 130 g and a volume of 5 cm^3? please explain or im gonna fail 7th grade science

26 g/cm³

Explanation:

Given data:

Mass of object = 130 g

Volume of object = 5 cm³

Density of object = ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

d = 130 g/ 5cm³

d =  26 g/cm³

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!

if you need further assistance, let me know: )
