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

Explanation:

It is known that in 1 mole there are $6.023 \times 10^{23}$ atoms or molecules.

It is given that there are $7.2 \times 10^{23}$ carbon molecules. Therefore, calculate the moles as follows.

     Number of moles = $\frac{7.2 \times 10^{23} molecules}{6.023 \times 10^{23} molecules/mol}$

                                   = 1.196 mol

Thus, we can conclude that there are 1.196 mol in $7.2 \times 10^{23}$ carbon molecules.
