Question

Explanation / Answer

One interpretation of the balanced equation TiCl4 +   2Mg   --> Ti   + 2MgCl2 is that 2 moles of Magnesium are required to react with 1 mole oftitanium chloride, using the balanced coefficients... Another way of saying the same thing is that 48.6 grams ofmagnesium (2 mol) are required to react with 189.7 grams ( 1 mol)of Titanium chloride To solve your problem, first convert 83.6 grams of TiCl4to mol and then use the above information to calculate how muchmagnesium is required for this much TiCl4. 83.6 g TiCl4 x 1 mol/189.7 grams = 0.44 mol TiCl4 0.441 mol TiCl4 x 2 mol Mg/ 1 molTiCl4 = 0.88 mol Mg 0.88 mol Mg x 24.3 g/mol = 21.4 grams Mg
