The molecular weight of water is 18 (2+16). This means that in 18g of water is one mole.

So in 180 grams of water, there are 10 moles of water
In each mole of a substance, there is #6.023 times 10^23# molecules/atoms

So, in 10 moles, there is #60.23 times 10^23# molecules or #6.023 times 10^24# molecules of water.
