The heat of neutralization for this acid-base reaction is measured by using A coffee cup calorimeter the reaction is as . HBr(aq) + NaOH(aq) → NaBr(aq) + H2O(l)
where 35.0 mL of 0.250 M Hydrofen bromide is mixed with 60.0 mL of 0.325 M sodium hydroxide. initially the temperature was= 20.500 oC of Both solutions . eaction has finished,and the temperature of the mixture reached to 21.640o C. Determine the Number of moles when it is used to calculate the heat of neutralization when it is given that : heat capacity of the calorimeter =28.7 J/oC ,the specific heat of the mixture =4.184 J/goC, density of the solution =1.02 g/mL.
