What is the density of the football?
g/cm3
calculate the density of the football. use the formula
d=m/v
where d is the density, m is the mass, and v is the volume. record your calculations in table b of your student guide.

Your question is lacking the necessary parameters, so I will assume the values to enable me solve it:

To find the density of the football;

Density is simply mass per unit volume of an object such as a football.

Mathematically, the density of an object is given by the formula;

Substituting the assumed values into the above formula;

Therefore, the density of the football is .

Note: You can substitute the appropriate parameters into the formula to get the exact density of the ball.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
