A .2726g sample of a metal was dissolved in the 50.00mL of .5000M HCl. After all of the metal had dissolved, the left over acid was titrated with the 0.1054M NaOH. If 24.36 mL of 0.1054M NaOH was needed to neutralize the leftover acid, explain what the atomic mass of the metal was when the metal dissolved to form a M2+ ion.
