It is best to have a _____ percent yield and a _____ percent error. The options are HIGH and LOW.

Answer 1

% yield is how much stuff you get from the reaction. Higher is good because it means your reactants are used more efficiently.

% error is how accurate your measurements are. Lower is better.

Answer 2

HIGH % yield

LOW % error

Yield is how much product you make. The more product you make, the more efficient it is.

Percent error is how far you are from the "correct" answer. A low percent means you are not far from your "correct" or expected answer. A high percent means you are far from it.
