- A dry coffee-cup calorimeter is weighed on a balance; its mass is 6.105g - 25.0mL of 2.19M aluminum nitrate solution is added to the calorimeter: the mass of the calorimeter with this solution volume is measured to be 31.045g. - 25.0mL of 3.27M sodium oxalate solution is mixed with the sodium phosphate solution already in the calorimeter, after a maximum temperature change is achieved, the mass of the calorimeter and its contents is measured to be 56.009g. - Standard Enthalpy of the reaction is 140.3kJ a) Calculate the amount of heat absorbed or released by the reaction b) calculate the moles of the solid that could be produced based on the moles of each reactant added to the calorimeter c) based on the limiting reactant from part b, calculate the enthalpy change for the precipitation of one mole of the solid d) calculate the formation enthalpy for the solid based on the result from part c and the formation enthalpies for the two reactants
