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

Sedaia [141]

$0.612 \times 10^{7} \text { moles of } \mathrm{CO}_{2}$ are present in $3.69 \times 10^{30} \text { molecules of } \mathrm{CO}_{2}$

<u>Explanation:</u>

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,

$1 mol of element =6.02 \times 10^{23} molecules of element$

As here $3.69 \times 10^{30}$ molecules of carbon di oxide is given. So the moles in it will be

No. of moles of carbon dioxide = $\frac{3.69 \times 10^{30}}{6.02 \times 10^{23}}$

No. of moles = $0.612 \times 10^{7}$ moles of carbon dioxide.

Thus,

$0.612 \times 10^{7}$ of carbon dioxide are present in $3.69 \times 10^{30} \text { molecules of } \mathrm{CO}_{2}$ .
