Question

How many moles in 3.69 x 10^30 molecules of carbon dioxide?

Answer 1

`0.612 * 10^(7) \text { moles of } \mathrm{CO}_(2)` are present in
`3.69 * 10^(30) \text { molecules of } \mathrm{CO}_(2)`

Step-by-step explanation:

It is known that each mole of an element is composed of avagadro's number of molecules. So if we need to determine, we need to divide the number of molecules with the avagadro's number.

So,

`1 mol of element =6.02 * 10^(23) molecules of element`

As here
`3.69 * 10^(30)` molecules of carbon di oxide is given. So the moles in it will be

No. of moles of carbon dioxide =
`(3.69 * 10^(30))/(6.02 * 10^(23))`

No. of moles =
`0.612 * 10^(7)` moles of carbon dioxide.

Thus,

`0.612 * 10^(7)` of carbon dioxide are present in
`3.69 * 10^(30) \text { molecules of } \mathrm{CO}_(2)`.
