A student wants to analyze the composition of a sample of an unknown metal alloy. They dissolve a 0.500g sample of the alloy in hydrochloric acid to form a solution which is then titrated with sodium hydroxide (NaOH) to neutralize the acid. The volume of the NaOH solution required is 16.50 mL. Assuming the acid reacts with the metal in the alloy according to the formula: M + 2HCl → MCl₂ + H₂, what is the percent composition by mass of Metal M in the alloy?
