A 25-mL sample containing Hg2 was treated with 10.0 mL of 0.0754 M EDTA to complex all the Hg2 and leave excess EDTA in solution. The excess EDTA was then back titrated, requiring 2.17 mL of 0.0264 M Ca2 . What was the concentration of Hg2 in the original solution

Which of the following pressures is equal to 760 mm hg? 2.0 atm 101.3 pa 101,300 kpa 101,300 pa

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.
