A sample of gas in a cylinder as in the example in Part A has an initial volume of 40.0 L , and you have determined that it contains 1.60 moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 10.0 L . How many moles of gas (n2) remain in the cylinder

How is the composition of a meteorite relevant to finding out the composition of earth's core?

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.
