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.
Today the ISO has grown to a confederation of delegates representing over 150 countries and has published over 16,500 international standards. They meet on a regular basis to further develop new and existing management standards.
