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