Here's why:
* Mole: A mole is a unit of measurement that represents a specific number of particles (atoms, molecules, ions, etc.). This number is known as Avogadro's number, which is approximately 6.022 x 10^23.
* Ethanol (C2H5OH) and Ethane (C2H6): These are two distinct molecules with different chemical formulas and structures.
* Equal Moles, Equal Molecules: One mole of any substance will always contain Avogadro's number of molecules. Therefore, one mole of ethanol and one mole of ethane will both have the same number of molecules.
Important Note: While the number of molecules is the same, the mass, volume, and other properties of one mole of ethanol and one mole of ethane will be different due to their different chemical compositions.
