1 mole of Ethanol molecule contains an Avogadro Number of molecules

1 mole of Ethanol molecule contains 6.02 * 10²³ molecules


3.5 moles of Ethanol will then contain:        3.5 * 6.02 * 10²³

                                                                       = 2.107 * 10²⁴ molecules.

Answer: There are [tex]2.1077\times 10^{24}[/tex] number of molecules in the given moles.

Explanation:

We are given:

Number of moles of ethanol = 3.5 moles

According to mole concept:

1 mole of a compound contains [tex]6.022\times 10^{23}[/tex] number of molecules.

So, 3.5 moles of ethanol will contain = [tex]3.5\times 6.022\times 10^{23}=2.1077\times 10^{24}[/tex] number of molecules.

Hence, there are [tex]2.1077\times 10^{24}[/tex] number of molecules in the given moles.
