A 1.766-g sample of impure sodium oxalate (Na2C2O4) is dissolved in water and titrated to methylred end point with 0.250 M HCl. The reaction is: Na2C2O4(s) + 2HCl(aq) o H2C2O4(aq) + 2NaCl(aq) If 44.15 mL of the acid is used for this reaction, what is the percent by mass of sodium oxalate in the sample?

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.
