Question

If you are given the number of molecules in an unidentified chemical compound can you calculate the number of moles in this sample

Answer 1

Yes.
Mols x Avogadro's Constant (6.02x10^23) = number of molecules.
You can rearrange that formula to find the number of Mols. Hope this helped

Answer 2

Answer: By using mole concept

Step-by-step explanation:

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* 10^(23)` number of molecules.

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

For Example: A sample of water contains
`10.8396* 10^(23)` number of molecules.

So, by using mole concept:

`6.022* 10^(23)` number of molecules are contained in 1 mole of a compound.

So,
`10.8396* 10^(23)` number of molecules will be contained in
`(1)/(6.022* 10^(23))* 10.8396* 10^(23)=1.8 moles` of water
