When reacting acetic anhydride with salicylic acid, which expression best reflects the way to calculate the theoretical yield of aspirin in g?

Which expression best reflects the way to calculate the enthalpy of the reaction of MgO and HCl to form MgCl2 and H2O (ΔHrxn,MgO+HCl) in kJ/mol from the released heat of reaction, given the following data? Mass of MgO 0.511 g Specific Heat of HCl soln (water) 4.184 J/g-deg Change in temperature, ΔT 4.4 deg Volume of HCl added 101.2 mL Concentration of HCl added 0.997 M MW, MgO 40.304 g/mol Density of HCl solution 1.016 g/mL ΔH1 (experimentally determined) -466.8 kJ/mol ΔHf,water -285.8 kJ/mol

In an experiment that reacts a trivalent metal with HCl to generate molecular hydrogen, the following data comes about.  What is the MW of the metal in g/mol? Mass of unknown trivalent metal sample, Munk: 0.032 g Volume of trapped air (initial), Vi: 1.6 mL Volume of air after experiment (final), Vf: 44.0 mL Room temperature, T: 21.4 °C Partial pressure of H2, PH2: 748.4  torr Gas constant, R: 0.0821 L•atm•(mol•K)-1 1 atm: 760 torr
