The energy densities of various types of coal are listed below: Anthracite 35kJ/g Subbituminous 31kJ/g Bituminous 28kJ/g Lignite 26kJ/g An unknown sample of one of these coals is burned in an apparatus with a calorimeter constant of 1.3kJ/°C. When a 0.367-g sample is used, the temperature change is 8.75°C. Which type of coal is the sample?
