Question

# of particles of one mole of a water

Answer 1

Answer:

Because by definition a mole is the amount of a certain substance (atoms, molecules etc) that contains 6,022 x 10E23 atoms or molecules (etc...) of that substance.

All molecules of water are the same and all atoms of oxygen are the same therefore 6,022 x 10E23 atoms of oxygen will always weigh the same and 6,022 x 10E23 molecules of water will always weigh the same.

The number 6,022 x 10E23 comes from the fact that Carbon-12 was used as basis and there are exactly 6,022 x 10E23 atoms of Carbon-12 in 12 grams of Carbon-12.
