**chem 1406**

ok that's where i got the number 8260000kj=kj uuuggggh i don't know what im doing wrong!!

**chem 1406**

ok so (2000moles/1)(4130kj/1mole) = (kj/2000 moles)(2000 moles/1) (2000)(4130kj) = kj now what?

**chem 1406**

ok so then i set it up wrong it should be 4130 kj/1 mole = 2000 moles/kj and that time i got 8260000 i don't know if that is right because the kj would cancel out too

**chem 1406**

i got 2.065 kJ/mole

**chem 1406**

so i would set the problem up like this.... 4130kJ/1 mole = xkJ/2000 moles ???

**chem 1406**

Consider: C7 H16(L) + 11 O2 (G) yields 7 CO2 + 8 H2O (L) delta Hreaction = -4130 kJ How much energy is released when 2,000 moles of C7 H16 is combusted?
