Objectives: 

1. Students will be able to successfully calculate an average atomic mass based off of isotopic data.

2. Students will successfully calculate the average atomic mass of Candium. 

Warm-Up: (Part 1)

A container holding a mixture consists of the following:

57- Peanuts    21- Raisins    128- Granola Pieces    83- Oatmeal Pieces

What percentage of this mixture is Granola?

Warm-Up: (Part 2)

What would the average atomic mass be for element "X" with the following isotopic data:

                   ⁴²X = 25.0 %      ⁴³X = 5.00 %      ⁴⁶X = 70.0%

Mass of X-42 = 42.512 amu

Mass of X-43 = 43.195 amu

Mass of X-46 = 46.231 amu
