Hydrocarbons have about 2 hydrogens (CnH2n+2 for alkanes, CnH2n for
Alkenes,
etc.) for every carbon. Using decane (C10) or undecane (C11) to represent
jet
fuel may be reasonable - the density looks about right. You can figure an
average molecular weight somewhere in the large neighborhood of 150
#/#-mole
(that'll get you a rough number for molecules in a ton). The chemical
balance
and actual computation are left as an exercise for the student...

Do I understand that you don't know?


Actually Mike he just gave you the information you
need to work put the answer

Knowing the hydrogen/carbon ratio lets you work out the
water/co2 balance in the products of combustion
and with the atomic weights you can figure out the
rough masses , assuming complete conbustion.

I can't. I was looking for some kind soul to help me.
