Explanation :
Density of an object can determine using mass and volume. We can measure mass and volume of various sports ball, both regular shaped ball and irregular shaped ball.
Density for regularly shaped ball and that of irregularly shaped ball is different.
Suppose that mass of an object is 100g and the volume is 
. So, using this data we can find density of that object as
That depends on how much of it you have, but it's a hugely enormous gigantic number in even the smallest sample.
You can see from the formula that there are 12 atoms in every molecule of the stuff !
