A Volume of 500

Question 169

Short Answer

A volume of 500.0 mL of 0.220 M HCl(aq)was added to a high quality constant-pressure calorimeter containing 500.0 mL of 0.200 M NaOH(aq). Both solutions have a density of and a specific heat of 4.184 J g−1 °C−1. The calorimeter had a heat capacity of 850.0 J °C−1. The temperature of the entire system rose from 25.60 °C to 26.70 °C. Calculate the heat of reaction, in kJ, per mole of NaOH(aq). A volume of 500.0 mL of 0.220 M HCl(aq)was added to a high quality constant-pressure calorimeter containing 500.0 mL of 0.200 M NaOH(aq).
