How is counting a truckload of pennies like counting the atoms in 10.0 g of aluminum? How is it different?

Explanation:

A truckload of pennies is quite a very large amount of problem to solve. A truck can carry a lot of coins which can be up to several millions in number approximately.

This is similar to counting the number of atoms in 10.0g of aluminium.

 In a mole of any substance, there are 6.02 x 10²³ atoms.

            number of moles  =

                    molar mass of Al  = 27g/mole

           number of moles  =   = 0.37moles

  Number of atoms  = 0.37 x 6.02 x 10²³ = 2.23 x 10²³ atoms

In 10g of aluminium, there are 2.23 x 10²³ atoms. It is even much more tedious to count.

Difference;

We can see the pennies in the truckload. They are discrete. It is impossible to see atoms in a substance this way.

Also, the number of atoms in 10g of aluminium is more than that of pennies in a truckload.

58750.08068 is the answer i think
