Question

If you have 4.72 x 10^24 atoms of Carbon, how many moles of Carbon do you have?

Question 5 options:


2.84 x 10^48 moles of carbon


4.12 x 10^24 moles of carbon


4.72 x 10^24 moles of carbon


7.84 moles of carbon

Answer 1

`7.84\ \text{moles}`

Step-by-step explanation:

Number of atoms of carbon =
`4.72* 10^(24)`

Avogadro's number =
`6.022* 10^(23)\ \text{mol}^(-1)`

Here we have to divide the number of atoms by the Avogadro's number

`(4.72* 10^(24))/(6.022* 10^(23))=7.83792\approx 7.84\ \text{moles}`

The moles of carbon are
`7.84\ \text{moles}`.
