Stoichiometry tends to be a challenging topic for many students due to the many different types of stoichiometry problems.
This worksheet explains how to calculate mole ratios, in both unbalanced and balanced equations, in a very accessible, step-by-step manner. The worksheet is designed to be approached video game style, where students need to achieve mastery at one level prior to moving on to the next. Multiple examples and a complete answer key are included.
This worksheet is a part of my "Student friendly Stoichiometry worksheet - Complete Package", which includes 4 additional levels. If you like this package, you can also purchase Levels 3 to 6 separately.
