In a calorimeter, we added 50 mL of 1M HCl to 50 mL of 1.1 M NH3 which produces NH4Cl. If the temperature increased 5.0 degrees Celsius, what is the molar enthalpy? We weren't given a heat capacity for the calorimeter but it was made out of a glass beaker and the heat capacity of glass is 0.840 J/g^oC found on google.

In a constant-pressure calorimeter, 75.0 mL of 0.790 M H2SO4 was added to 75.0 mL of 0.360 M NaOH. The reaction caused the temperature of the solution to rise from 23.01 °C to 25.46 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184 J/g·K, respectively), what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
