sorry the final temp is 30.19 C
For this cerise, you can simte the described conditions by changing the values in the Run Experiment tool under the Experiment tab, in the simulation. The hint run though each step in the calculation, where the equations are given before this part. The second hint calculates the temperature change, which is the only step that requires the s tation Use the simulator to react mL of 19 MHNO, with 78 mL of 1.7...
