In the world of chemistry, a 'mole' is a number of something... a very large number of something.

Just as a 'dozen' is 12 of something, a 'mole' is about 6.02 * 1023 of something.

In chemistry, we like to measure the number of atoms or molecules in moles.

If one mole is equal to 6.02 * 1023 atoms, and you have 8.00 * 1023 atoms, then how many moles do you have?

Round your answer to two decimal places.

Answer:

1.33 mol

Explanation:

(8 × 10^23)/(6.02 × 10^23)

=1.32890365449

= 1.33 mol

Answer: The number of moles of substance is 1.33 moles.

Explanation:

We are given:

Number of atoms = [tex]8.00\times 10^{23}[/tex]

According to mole concept:

[tex]6.022\times 10^{23}[/tex] number of molecules occupy 1 mole of a substance.

So, [tex]8.00\times 10^{23}[/tex] number of atoms will occupy = [tex]\frac{1}{6.022\times 10^{23}}\times 8.00\times 10^{23}=1.33mol[/tex] of a substance.

Hence, the number of moles of substance is 1.33 moles.
