In the lab you made some copper using this chemical reaction: CuCI2. 2H20 Mg --> MgCI2 Cu 2H20 Suppose you used a LOT of copper (Il) chloride dihydrate, such as 145.0 grams. How many grams of magnesium would you need for this reaction? Just calculate how many grams of magnesium the reaction would need. Do not multiply this by 1.5 the way you would do in the lab. The molar mass of CuCI2. 2H20 is 170.48 g/mol and the molar mass of magnesium is 24.305 g/mol. The molar mass of copper is 63.546 g/mol. Please answer to one digit after the dot. - _ § magnesium
