How many molecules of h2o are in 97.28 g of h2o?

The mass of water = 97.28g

The molecular mass of water is

18.01528 g/mol

No of moles of water is 97.28/18.01528 = 5.3998

Approximately 5

Therefore, there are 5 molecules of water in 97.28g of water.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
