An irregularly shaped solid which has a mass of 10.283g was placed in a graduated cylinder containing an inert liquid. the initial volume of liquid was read as 6.26ml. the solid was completely submerged in the liquid and the total volume of the liquid plus solid was read as 8.89ml. calculate the density of the solid.

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.
