Answer :

Explanation:

Number of moles is defined as mass divided by molar mass.

Mathematically, No. of moles = [tex]\frac{mass}{molar mass}[/tex]

It is known that molar mass of water ([tex]H_{2}O[/tex]) 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 = [tex]\frac{mass}{molar mass}[/tex]

= [tex]\frac{97.3 g}{18 g/mol}[/tex]

= 5.40 mol

Thus, we can conclude that there are 5.40 moles of H2O are equivalent to 97.3 grams of H2O.
