Understanding the Concept

* Avogadro's Number: A mole is a unit of measurement that represents a specific number of particles (atoms, molecules, etc.). This number is Avogadro's number, which is approximately 6.022 x 10²³ particles per mole.

Calculation

1. Start with the moles of H₂O: 0.943 moles H₂O

2. Multiply by Avogadro's Number:

0.943 moles H₂O * (6.022 x 10²³ molecules H₂O / 1 mole H₂O)

3. Cancel out the units: The "moles" unit cancels out, leaving you with molecules.

4. Calculate: The result is approximately 5.68 x 10²³ molecules of H₂O.

Answer: 0.943 moles of H₂O is equivalent to approximately 5.68 x 10²³ molecules of H₂O.
