39. An example of an exothermic fusion reaction is H+ H+ H+ n.
The energy released from this reaction is due to a small change in mass that occurs as the
re transformed into the products. Using the mass values given under the heading
"Nuclear Chemistry" in the Science Data Booklet, calculate the change in mass per mole of
hydrogen-2 that occurs in the reaction.
