A10.0-ml sample of 1.0 m nahco3 is titrated with 1.0 m hcl (hydrochloric acid). approximate the titration curve by plotting the following points: ph after 0 ml hcl added, ph after 1.0 ml hcl added, ph after 9.5 ml hcl added, ph after 10.0 ml hcl added (equivalence point), ph after 10.5 ml hcl added, and ph after 12.0 ml hcl added.

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.
