This is a single 2-page worksheet for determining percent composition, empirical formulas, and molecular formulas of compounds. There are a total of 10 questions.
Answer key is included.
The download includes a handout master (.pdf) that includes one worksheet, and answer key.
This product is designed to help students prepare for the following learning objective:
•Learning Objective 1.1: The student can justify the observation that the ratio of the masses of the constituent elements in any pure sample of that compound is always identical on the basis of the atomic molecular theory.
•Learning Objective 1.2: The student is able to select and apply mathematical routines to mass data to identify or infer the composition of pure substances and/or mixtures.
•Learning Objective 1.3: The student is able to select and apply mathematical relationships to mass data in order to justify a claim regarding the identity and/or estimated purity of a substance.
•Learning Objective 1.4: The student is able to connect the number of particles, moles, mass, and volume of substances to one another, both qualitatively and quantitatively.
While designed specifically for AP Chemistry, this product is also useful for any level of chemistry that covers empirical and molecular formulas (regular, honors, IB, college).
