Mathematically, No. of moles =
It is known that molar mass of water () is 18 g/mol and it is given that mass is 97.3 grams.
Hence, calculate the number of moles of water as follows.
No. of moles =
=
= 5.40 mol
Thus, we can conclude that there are 5.40 moles of H2O are equivalent to 97.3 grams of H2O.
