Question
C2H2(g)+ 5/2o2(g)-> 2Co2(g)+ H2o(g)+ 1255.8KJ
how many grams of C2H2 are reacted when 310 KJ of heat are released?
I left the oxygen (O) lowercase in the equation so it does not get mixed up with zero.

USUALLY we don't mix and o with an O. Placing a space, as in 5/2 O2 takes care of that possible mix up.
26 g C2H2 releases 1256.8 kJ.
26 g x (310 kJ/1255.8 kJ = ? g C2H2.
