Two answers with results 203% which does not seem reasonable or possible - and two at 95.... % which seems better: Check which is correct: Equation: Mg + 2HCl → MgCl2 + H2 1 mol Mg produces 1 mol MgCl2 Molar mass Mg = 24.305g 3.304g Mg = 3.304/24.305 = 0.1359 mol Mg This will produce 0.1395 mol MgCl2 Molar mass MgCl2 = 95.21g/mol 0.1359 mol = 0.1359*95.21 = 12.94g MgCl2 is the theoretical production. But you claim to have produced 26.3g - I think grams - you do not specify So the % yield is 26.3/12.94*100 = 203% The impossible answer is correct according to the figures provided. What is wrong with the question? Well, nothing wrong it appears - the 95% answerers were smart enough to consider the hydrated salt. Good Thinking!! But in fairness I think that the question should have indicated that the product was the hexahydrate.

keep this in mind: when a metal reacts with an acid it produced HYDROGEN. This can be tested for by putting a lighted splint near the mouth of the test-tube...there is a loud popping sound of ydrogen exploding (mini-explosions hehhe i love that cute sound)

Hydrogen. Sorry not to give you a fuller explanation - tired after working all day. Hope someone else has given you the equation
