What is the H and the error on the enthalpy?

A student collected the data shown below in order to determine the AH for a 3e battery reaction. What is the standard enthalpy of reaction (in kJ/mol) that they determined and what is the associated error? Report your answer to the appropriate number of significant figures. Do NOT use scientific notation. Any numbers less than 1 MUST have the leading zero, for example 0.05 and NOT.05. Assume the error on the temperature is t0.03 C Enter the AH here - and the error on the enthalpy here - EVT(C) 1.60974 2.33 1.60813 8.53 1.60781 12.97 1.60700 15.65 1.60678 20.44 1.60498 25.00 1.60563 25.00 1.60411 29.82 1.60394 34.28 1.60308 36.40 1.60296 41.48 1.60100 46.98
