An ore sample is known to contain copper sulfate pentahydrate, CuSO4•5H2O. If a 9.661 g sample of the ore loses 1.0447 g of water when heated strongly, what is the maximum mass, in grams, of CuSO4•5H2O that could have been in the sample? (MW of CuSO4•5H2O = 249.55 g/mol)

Consider the reaction of a(g) + b(g) + c(g) => d(g) for which the following data were obtained: experiment initial [a], mol/l initial [b], mol/l initial [c], mol/l initial rate, mol/l. s 1 0.0500 0.0500 0.0100 6.25 x 10^-3 2 0.100 0.0500 0.0100 2.50 x 10^-2 3 0.100 0.100 0.0100 1.00 x 10^-1 4 0.0500 0.0500 0.0200 6.25 x 10^-3 what is the rate law for the reaction?
