Beau · Answer 1

I mole of water has an Avogadro number of molecules.

1 mole = 6.02 * 10^ 23 molecules.

6.02 * 10^ 23 molecules = 1 mole of water

1 molecule = 1 / (6.02 * 10^23) mole of water

2.0 * 10^22 molecules would have = (2*10^22) * 1 / (6.02*10^23)

= 0.033

2 * 10 ^22 molecules of water would have 0.033 moles of water.
