molecules in a mole.
There are
18.01528
grams of water per mole of water.
These can be figured out using the concept of moles and molecular weight. I have attached a video that provides a good explanation.

Answer:
So the no of molecules of 54g of water is 1.8 * 10 to the power 24
Explanation:
To find the mole of 54gm of H2O=
As we know Number of moles = mass/molar mass
So, by using water molar mass to find the no. of moles present in water:-
54g of H2O * 1 mole of H2O/18.015g= 2.997502
than, by using the avogado number to find the number of molecules of water:-
2.997502* 6.022*10 to the power 24/ 1 mole H2O = 1.8 * 10 to the power 24
