When studying the composition of substances, it is common to come across calculations involving the amount of matter. In a chemistry experiment, a student needs to calculate the number of water molecules (H2O) present in a 10-liter bucket of water. Considering that the molar mass of water is approximately 18 grams per mole, determine the number of water molecules present in the bucket and explain the calculation process in detail, using the concept of moles and Avogadro's constant. Consider that the bucket of water is at normal temperature and pressure.

9.01 x 10^23 water molecules

1.00 x 10^24 water molecules

6.02 x 10^23 water molecules

3.34 x 10^26 water molecules

18.0 x 10^24 water molecules
