<u>Answer:</u> By using mole concept

<u>Explanation:</u>

We are given:

An unknown compound having some number of molecules.

To calculate the number of moles that are contained in a sample, we use mole concept:

According to mole concept:

1 mole of any compound contains 6.022\times 10^{23} number of molecules.

Using this relation and applying unitary method, we can easily calculate the number of moles of a compound.

<u>For Example:</u> A sample of water contains 10.8396\times 10^{23} number of molecules.

So, by using mole concept:

6.022\times 10^{23} number of molecules are contained in 1 mole of a compound.

So, 10.8396\times 10^{23} number of molecules will be contained in \frac{1}{6.022\times 10^{23}}\times 10.8396\times 10^{23}=1.8 moles of water
