Question

Convert 180 grams of water to molecules of water?

Answer 1

`6.023 times 10^24` molecules of water

Explanation:

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.
