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 \(2.1077\times 10^{24}\) 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 \(6.022\times 10^{23}\) number of molecules.

So, 3.5 moles of ethanol will contain = \(3.5\times 6.022\times 10^{23}=2.1077\times 10^{24}\) number of molecules.

Hence, there are \(2.1077\times 10^{24}\) number of molecules in the given moles.
