The average atomic mass of copper is 63.55 amu. If the only two isotopes of copper have masses of 62.94 amu and 64.93 amu, what are the percentages of each? Calculate the GCF, GCD or HCF and see work with steps. Learn how to find the greatest common factor using factoring, prime factorization and the Euclidean Algorithm.

Calculating the atomic mass of C use: Mass ratio of 13C/12C (using a mass spectrometer) is 1.0836, so the mass of the C-13 isotope is (1.08036)(12 amu exactly) = 13.00336 amu. Note: Atomic mass unit (amu) is the unit for relative atomic masses of the elements; such the mass of carbon-12 is exactly 12 atomic mass unit. 1 amu = 1.6605x10-24 grams Official Google Search Help Center where you can find tips and tutorials on using Google Search and other answers to frequently asked questions.
