mols HgO = grams/molar mass = ?
Using the cofficients in the balanced equation, convert mols HgO to mols OH^-
then convert that to mols HClO4.
Finally, M HClO4 = mols HClO4/L HClO4
A solution of HClO4 was standardized by dissolving 0.3745 g of primary standard grade HgO in a solution of KBr.
The liberated OH- required 37.99 mL of the acid to be neutralized. Find the molarity(M) of HClO4.
The given balanced chemical equation is:
HgO + 4Br- + H20 ===> HgBr4^2- + 2OH-
