(b) How many grams of ethanol does he need to burn in order to heat up 250 ml of water (MW= 18.02 gmol') from 20°C to 85°C at constant pressure? Assume that all the heat generated is transferred to the water with 100% efficiency and that the molar heat capacity of water, C, is 75.33 JK'mol and is independent of temperature.
