2.00 g of NaOH are dissolved in water to make 4.00 L of solution. What is the concentration of hydronium ions, [H3O+], in this solution? How can I work this problem? The book was no help.

Best ResponseYou've already chosen the best response.0So 2.00g of NAOH is equal to how many mol of NaOH? Use the molar mass? I hate stoichiometry.
