Answer:

65.25 grams of water

Explanation:

Moles of H2 = mass/ M.w

= 7.25g /2

=3.625 mol H2

Moles of H2O = moles of H2 = 3.625 mole

Mass of H2O = mol * molar wight

= 3.625 * 18 = 65.25 g H2O

Suggest the pH of the solution made when potassium oxide dissolves in water.
Varvara68 [4.7K]

Answer:

Since KOH is a strong base, the solution completely ionizes into K+ and OH- when in water. The reaction KOH --> K+ + OH- takes place. The concentration of [ OH- ] can then be used to calculate the pOH of the solution. pH = 14 - pOH = 14 - 1.48 = 12.52
