Answer :

Answer : 5.405 moles of [tex]H_2O[/tex] are equivalent to 97.3 grams of [tex]H_2O[/tex]

Solution : Given,

Mass of [tex]H_2O[/tex] = 97.3 g

Molar mass of [tex]H_2O[/tex] = 18 g/mole

Formula used :

[tex]\text{ Number of moles}=\frac{\text{ Given mass}}{\text{ Molar mass}}[/tex]

or,

[tex]\text{ Number of moles of }H_2O=\frac{\text{ Given mass of }H_2O}{\text{ Molar mass of }H_2O}[/tex]

Now put all the given values in this formula, we get the moles of [tex]H_2O[/tex]

[tex]\text{ Number of moles of }H_2O=\frac{97.3g}{18g/mole}=5.405moles[/tex]

Therefore, 5.405 moles of [tex]H_2O[/tex] are equivalent to 97.3 grams of [tex]H_2O[/tex]
