ATP Phosphate Energy

I am trying to find out how may Joules (kjoul.) are bound
up in the high energy phosphate bond of ATP? In other words when ADP is
converted to ATP how much energy is in that new single covalent bond?
There are several interesting posts regarding the energy stored by ATP in the
NEWTON AAS Molecular Biology Archive
( http://www.newton.dep.anl.gov/askasci/mole00.htm ).
The most directly relevant to your inquiry is a fairly old answer to a question
on ATP Energy, in which Dr. Peter Faletra indicates that "the amount of energy
[ATP-->ADP+ PHO4~substrate] is about -30.5 kilojoules.mole-1"
( http://www.newton.dep.anl.gov/askasci/mole00/mole00072.htm ).
My apologies for the delay in responding & I hope that this info. is still helpful,
