What type of mistake could lead to getting over 100% on a calculated percent recovery? On my calculation I ended up with 115%...?

measurement error. Let's say you had A + B = C where C is the material you want. Let's also say B is the limiting reactant so it's the one you measured, did the reaction and then recovered and weighed C.
1. You used more B than you thought. More B, more C.
2. You measured B wrong for whatever reason. Let's say you weighed C and didn't subtract the filter paper or C was still wet (water = more mass that you would have thought was C) or there was another product that you didn't wash away so it was weighed with the C and again, too much "C".
Or you just made a mistake in calculating how much C you should have made such as the wrong coefficients or the wrong atomic or molar masses. Just some ideals.
