Question

The number of molecules in one liter of water isone liter of water is

Answer 1

Answer:

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022 *10 23 * 55.556 = 3.346 * 10 25 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*10 26 atoms in a liter of water.
