Question

2B5H9(l) + 12O2(g) -->5B2O3(s) + 9H2O(l) Calculate thet kJ of heat released per gram og the compoundreacted with oxygen. The standard enthalpy of formations forB5H9(l), B2O3(s) and H2O(l) are 42.84 kJ/mol, -1271.94 kJ/mol and-285.83 kJ/mol respectively. 2B5H9(l) + 12O2(g) -->5B2O3(s) + 9H2O(l) Calculate thet kJ of heat released per gram og the compoundreacted with oxygen. The standard enthalpy of formations forB5H9(l), B2O3(s) and H2O(l) are 42.84 kJ/mol, -1271.94 kJ/mol and-285.83 kJ/mol respectively.

Explanation / Answer

I got to that part, put how do you take that and turn it into kJ of heat released per gram of the compound reacted with oxygen?
