Suppose that 145 g of ethanol at 20◦c is mixed
with 235 g of ethanol at 84 ◦c at constant
atmospheric pressure in a thermally insulated
vessel. what is the ∆ssys for the process?
the specific heat capacity for ethanol is 2.42
j/g k.
answer in units of j/k.

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.
