Question

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

1.33 mol

Step-by-step explanation:

(8 × 10^23)/(6.02 × 10^23)

=1.32890365449

= 1.33 mol

Answer 2

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

Step-by-step explanation:

We are given:

Number of atoms =
`8.00* 10^(23)`

According to mole concept:

`6.022* 10^(23)` number of molecules occupy 1 mole of a substance.

So,
`8.00* 10^(23)` number of atoms will occupy =
`(1)/(6.022* 10^(23))* 8.00* 10^(23)=1.33mol` of a substance.

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