Astudent in lab combined 41.514 g of 1.0 m hcl solution (d = 1.0 g/ml) with 51.158 g of 1.0 m naoh solution (d = 1.0 g/ml) in a coffee cup calorimeter and recorded the temperature data below. calculate the enthalpy change (∆ ° ) per mole of hcl. (assume the specific heat capacity of the solution is the same as water, 4.184 j/g‧k.) hcl(aq) + naoh(aq) → h2o(l) + nacl(aq)
