..........Li2O + HOH ==> 2LiOH
1 mol Li2O produces 2 mols LiOH. How many moles Li2O do you have? I see mol = grams/molar mass
mol Li2O = 3.50 g Li2O/molar mass Li2O = ?
Then twice that gives moles LiOH produced.
M = mols LiOH/L LiOH.
M LiOH = moles OH^-; convert to H^+ by
H^+)(OH^-) = Kw ; then convert to pH.
pH = -log(H^+)
