Answer:

18.01528 grams.

Explanation:

Ther are 0.84 moles of [tex]H_{2}O[/tex] in 15.2 g of pure ice.

The molar mass of [tex]H_{2}O[/tex] is 18g.

To calculate the number of moles of a substance in a given mass of the sample, we divide the given mass by the molar mass of the sample,

Number of moles = given mass / molar mass

It is given that we have 15.2g of pure ice. Then the number of moles of [tex]H_{2}O[/tex] will be:

n = 15.2/18

n = 0.84 moles.
