Introduction to Chemistry
What is the primary difference between atomic mass and atomic number?
An element has two isotopes with masses of 10 AMU and 11 AMU, and percent abundances of 20% and 80%, respectively. What is the atomic mass of the element?
What is the conversion factor between AMU and kilograms?
Convert a percent abundance of 25% to fractional abundance.
Which of the following elements has multiple isotopes that significantly affect its atomic mass?
