Use of the Data Booklet is relevant to this question. A student carried out an experiment to determine the enthalpy change for the combustion of methanol. The following results were obtained by the student. [Table: start temperature of the water 20 °C, final temperature of the water 53 °C, mass of alcohol burner before burning 259.65 g, mass of alcohol burner after burning 259.15 g, mass of glass beaker plus water 150.00 g, mass of glass beaker 50.00 g] How much of the heat energy produced by the burning of methanol went into the water?
