A.P. Chemistry, Chapter 2: Objectives, Activities, and Homework
Read Chapter 2 and go over the chapter 2 notes provided.
Write problem solving steps you would use to solve the following types of problems:
1. Calculating weighted average atomic weight given isotope masses and percent abundance
2. Calculating percent abundance of two isotopes given their masses and the weighted average
atomic mass
3. Calculating mass given number of moles, or mols given mass
4. Determining number of particle present given mols or mass
5. Determining percent composition by mass of a compound given its formula
6. Determining an empirical formula given percent composition data
7. Determining a molecular formula given the empirical formula and the compound's molar mass
8. Determining a formula for a compound given mass data
9. Determining the formula for a hydrated compound
1. Describe the structure of an atom and use the periodic table (atomic number and atomic
mass) to determine the number of subatomic particles in an atom of any element
 HW, p. 100 #6
2. Define isotope and perform calculations to find percent abundance of an isotope,
weighted average atomic mass of the isotopes of an element, and the mass of one isotope.
