Question
If the heat of combustion for a specific compound is -1060.0 kJ/mol and its molar mass is 58.31 g/mol, how many grams of this compound must you burn to release 589.10 kJ of heat? I don't understand even how to begin this question, so can you walk it step by step?

dH = 1060 kJ/mol given off during combustion.
1060 kJ/mol x #moles = 589.10 kJ
Solve for # moles.
Then mols = grams/molar mass. You know molar mass and mols, solve for grams.
1060 kJ/mol x #moles = 589.10 kJ
Solve for # moles.
Then mols = grams/molar mass. You know molar mass and mols, solve for grams.
