Question

How many moles are in 7.2 x 10^23 carbon molecules?

(*round to the nearest hundredth and include the unit "mol C" after your number)

Question 6 options:

Answer 1

Step-by-step explanation:

It is known that in 1 mole there are
`6.023 * 10^(23)` atoms or molecules.

It is given that there are
`7.2 * 10^(23)` carbon molecules. Therefore, calculate the moles as follows.

Number of moles =
`(7.2 * 10^(23) molecules)/(6.023 * 10^(23) molecules/mol)`

= 1.196 mol

Thus, we can conclude that there are 1.196 mol in
`7.2 * 10^(23)` carbon molecules.
