When 155 mL of 0.1250 M H3PO4 at 24.00 deg C was mixed with 260.0 mL of 0.1000 M Sr(OH)2 at 24.00 deg C in a calorimeter (calorimeter constant = 40.4 J/\deg C), the temperature rose to 25.54\deg C. Calculate AH for the reaction. 2H3PO4(aq) + 3Sr(OH)2(aq) -> Sr3(PO4)2(s) + 6H2O(l). In calculating heat flow, treat the solutions as if they were pure water and ignore the small amount of water formed in the reaction.
