Calculating mass product from mole reactant. a. Given the balanced equation:
Fe + S > Fes
What mass, in grams, of S is consumed when 4 x 10^23 molecules of Fe is
consumed?
3. Calculating mole reactant to mass product
b.) Given the balanced equation:
2 ZnSO4 + 2 SrC12 > 2 SrS04 + 2 ZnCl2
What number of moles of Srcl2 is consumed when 125 g of ZnCl2 is produced?

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

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.
