A student designed a simple calorimeter to measure the combustion of ethanol in an open system (i.e. when gaseous, water is formed as a product). She collected the following data: Initial mass of ethanol burner (g) 2.56 Final mass of ethanol burner (g) 1.60 Volume of water (mL) 275 Initial temperature of water (°C) 24.8 Final temperature of water (°C) 32.1 Assuming no other errors in the experiment, what is the thermal efficiency, as a percentage, of the student's calorimeter?
