Answer:
[tex]4.92\text{ moles}[/tex]Explanation:
Here, we want to get the number of moles in the given mass of water
To get this, we have to divide the mass given by the molar mass of water
Mathematically:
[tex]Number\text{ of moles = }\frac{mass}{molar\text{ mass}}[/tex]The molar mass of water is 18 g/mol
Thus, we have the number of moles as:
[tex]Number\text{ of moles = }\frac{88.5}{18}\text{ = 4.92 moles}[/tex]
