An element has two isotopes. Isotope #1 has a mass of 159.3 amu and an abundance of 22.0%
Isotope #2 has a mass of 161.2 amu and an abundance of 78.0%.
What is the average atomic mass if this element?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
