What is the volume of an object with a density of 7.73 g/cm^3, and a mass of 5.40 x 10^2 g?

Volume of the object is,

Explanation:

It is given that,

Mass of the object,

Density of the object,

Let V is the volume of the object. We know that the mass divided by  volume of any material is called its density. The mathematical relation is given by :

So, the volume of the object is . Hence, this is the required solution.

a is the answer to this question

explanation:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
