First we need to find the molar mass of hydrogen in periodic table and multiply it with the 2 (quantity of hydrogen) (h2o) and then add 16 for oxygen.

Molar mas of H is 1.008 and quantity of H in h2o is 2. So 2x 1.008 + 16 = 18.016 g/1 mol and divide the molar mass with 25. So 25 divided by 18 is 1.39 moles.
