Answer:
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 = [tex]\frac{mass}{molar mass}[/tex]
molar mass of Al = 27g/mole
number of moles = [tex]\frac{10}{27}[/tex] = 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.
The truckload of pennies has been the discrete number of coins that has been assimilated in a truck. Atoms in 10 g Aluminum has been the smallest unit of the element that has not be visible with the eyes.
Difference in counting pennies and atoms
The number of atom in a known mass of sample has been calculated with the Avogadro's law. The number of atom in a mole of sample has been equivalent to the Avogadro number.
However, counting pennies has been performed in the chronological order. The counting has been performed for a long period of time.
Thus, the difference in counting pennies and atoms in Al has been given as atoms are not discretely counted while pennies are counted discretely.
