Hydrogen H2 is used as a rocker fuel. The hydrogen is burned in oxygen to produce water vapor.

2H2 + O2 ----> 2H2O
Delta H = -484 kJ

What is the enthalpy change per gram of hydrogen?

1 answer

delta H for 2 mols is -484 kJ.
So delta H for 1 mol is what? -484/2 = ??
And a mol of H2 has a mass of 2 grams, so what is delta H for 1 gram?
