As a third follow up to Question 3, some estimates are that 0.03 molesof uraninite can produce the energy equivalence of 1500 pounds of coal. Using 267 g/mol as a molar mass for uraninite, how many gramsof uraninite is needed to produce the energy equivalence of 1500 pounds of coal

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
