A 100. 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.
