Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of “reactions” (total molar mass = 5 grams).

Predict the products butane (c4h10) + oxygen —>

The number of moles of a given mass of a substance can be found without knowing its molecular formula or molar mass. true false
