Name: REPORT SHEETS Section Number: REPORT Your report should include the following Data Tables 4-1 and 4-2 Example calculations Answers to questions . . QUESTIONS 1. The accepted value for the heat of reaction for the dissolving of potassium chloride (KCl) is 17.2 kJ/mol of KCl. Determine the percent error in your measured value. Percent Errorexrimental-accepted (100) accepted According to the Calcium Chloride Handbook printed by Dow Chemical Company in 2003, the accepted value for the heat of reaction for the dissolving of calcium chloride dihydrate (CaCl, 2 H,O) is -44.8 k/mol of CaCl, 2 H,O. Determine the percent error in your mea- sured value. 2.

Explanation / Answer

1) Percent error =(experimental-accepted /accepted)*100

Your experimental value is found by experimenting in the lab

Accepted value is the literature value=17.2 KJ/mol

So,Percent error =(experimental-17.2 /17.2)*100
