The weighted atomic mass of these two isotopes is 63.5679 amu. To calculate this first multiply Copper-63's mass of 62.9296 amu by .6917 which gets you 43.5284. Then multiply Copper-65's mass of 64.9278 by .3083 which gets you 20.0395. Then add 43.5284 and 20.0395 to get the final answer of 63.5679 amu.
The Quality Matters standards assure that the online components of these courses promote learner engagement and provide students with all the tools and information they need to be successful learners. As discussed in the presentation, there are 41 specific review standards. This handout provides a listing of these standards. The Quality Matters toolset and process are: Based in national standards of best practice, the research literature, and instructional design principles. Designed to promote student learning.
The process of standardization can itself be standardized. There are at least four levels of standardization: compatibility, interchangeability, commonality and reference. These standardization processes create compatibility, similarity, measurement and symbol standards.
