Answer:

4.5 g

Explanation:

Given,

Moles of water = 0.25 moles

Molar mass of water ([tex]H_2O[/tex]) = [tex]2\times 1+1\times 16[/tex] = 18 g/mol

The formula for the calculation of moles is shown below:

[tex]moles = \frac{Mass\ taken}{Molar\ mass}[/tex]

Thus,

[tex]0.25\ moles= \frac{x}{18\ g/mol}[/tex]

Mass of water in 0.25 moles = 4.5 g
