Suppose 10.6g of zinc acetate is dissolved in 250.mL of a 0.20M aqueous solution of ammonium sulfate. Calculate the final molarity of zinc cation in the solution. You can assume the volume of the solution doesn't change when the zinc acetate is dissolved in it.Round your answer to 3 significant digits.
1.50 grams of butane (C4H10(g), ΔHf° = -125.6 kJ/mol) is completely combusted in the presence of excess oxygen. Assume that all the heat produced goes into heating a cylindrical plate of aluminum (d = 2.70 g/cm3) that is 2.00 cm thick and 10.0 cm ..
