If the heat if combustion for a specific compound is -1110.0 kJ/mol and its molar mass is 28.59 g/mol, how many grams of this compound must you burn to release 722.00 kJ of heat
Homework Answers
Number of mol of compound = heat / heat of combustion
=-722.00 KJ / -1110.0 KJ/mol
= 0.6504 mol
Mass of compound = mol * molar mass
= 0.6504 mol * 28.59 g/mol
= 18.6 g
Answer: 18.6 g
