WebAug 14, 2024 · Therefore, magnesium is the limiting reactant. Step 3: Because magnesium is the limiting reactant, the number of moles of magnesium determines the number of moles of titanium that can be formed: mol Ti = 8.23mol Mg = 1molTi 2mol Mg = 4.12mol Ti Thus only 4.12 mol of Ti can be formed.
