​

​Warm-up: Open up this quizizz and complete the following on a sheet of paper (for notes today):

Copper has two isotopes: Cu-63 (abundance = 69.2%, mass = 62.930 amu) and Cu-65 (abundance = 30.8%, mass = 64.928 amu). Calculate the atomic mass of copper​ using correct sig figs.​ Input your answer when we go to the next slide.
