Your toothpaste probably contains around 62g of fluorine per tube. How many miles are in one tube?

3.26mole

Explanation:

Given parameters:

Mass of fluorine  = 62g

Unknown:

Number of moles in one tube  = ?

Solution:

A mole is the amount of substance that contains the avogadro's number of particles.

We can find the number of moles of a substance by;

                  Number of moles  =

            Molar mass of Fluorine  = 19g/mol

Substitute in the equation:

           Number of moles  =   = 3.26mole

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
