In a coffee cup calorimeter, 50.00 mL of HNO3 (aq) and 50.00 mL of KOH(aq) were mixed. The temperature of the resultant solution increased 6.5 C. What is the Delta H of this reaction?

heat = masstotal*specificheatwater*6.5
= .050kg*2*6.5C*specific heat

so look up the specific heat of water in units of joules/kg-C

specific heat of water 4.185? Look in the back of your chemistry book or use the index to find an example
