A100.0 ml sample of 1.020 m hcl is mixed with a 50.0 ml sample of 2.040 m naoh in a styrofoam cup. if both solutions were initially at 24.53°c, and the enthalpy of the neutralization reaction is −57 kj/mole of h2o formed, what is the final temperature of the mixture? assume that the solution has a density of 1.00 g/ml and a specific heat of 4.184 j/g°c, and that the styrofoam cup has an insignificant heat capacity.
