If the heat of combustion for a specific compound is -1350.0 kJ/mol and its molar mass is 48.95 g/mol, how many grams of this compound must you burn to release 796.00 kJ of heat? One approach is to first calculate the number of moles of compound needed. Then convert from moles to grams using the molar mass.

Solution

moles = 796000/1350000= 0.58962962962962963 moles

thus mass required = 0.58962962962962963*48.95 = 28.8623703703703703885 g ANSWER
