how many molecules of water are produce from 100 grams of water?

Question

please try to have the closest number rounded up

Answer 1

100grams H2O * ( 1mol/ 18.015)

The grams are cancelled out so we get 100/18.015. Which is ~ 5.55 mols.

To find molecules, we need to use Avogadro's constant.

5.55mols * (6.022x10^23 molecules/ 1mol)

The mols cancel out leaving us with 5.55 * 6.022x10^23 molecules. Which is ~ 3.34x10^23 molecules of water are produced from 100 grams of water.
