A chemistry student was asked to calculate the number of moles of iron required to react with 1.20 mol of oxygen to produce iron(III) oxide. His calculation is shown below:

1.20 2 1 1 2=1.20

Is the student correct? Use evidence to support your answer.

How many moles are equivalent to 55.5g of nano3

Agas diffuses 1/7 times faster than hydrogen gas (h2). what is the molar mass of the gas? 100.10 g/mol 98.78 g/mol 86.68 g/mol 79.98 g/mol

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.
