Answer 1

Answer:

$3.75\text{ }\times\text{ 10}^9\text{ moles}$

Explanation:

Here, we want to get the number of moles present

Mathematically:

$1\text{ mole has 6.02 }\times\text{ 10}^{23}\text{ molecules}$

To get the number of moles in the given number of molecules, we divide the given number of molecules by the above

That would give:

$\frac{2.26\text{ }\times\text{ 10}^{33}}{6.02\text{ }\times\text{ 10}^{23}}=\text{ 3.75 }\times\text{ 10}^9\text{ moles}$
