Need mass fraction from individual reaction in multi-step chemistry combustion

  I am trying to simulate a Laminar diffusion flame using a multi-step chemical mechanism. For post-processing, I need to know the mass fraction of a compound formed from multiple reactions.
  I am using a "stiff chemistry solver".
  
  For example ;
  Reaction 1: A1+B1=C1+D1
  Reaction 2: A2+B2=C1+D2
  Reaction 3: A3+B3=C1+D3
  
  So, what is the mass fraction of C1 produced in Reaction 1,2 and 3 respectively? I am currently not able to find a way.

  The solver will track species creation, but not sure it'll tag which reaction created it. However, as you know the production rate of D1, D2 & D3 I suspect you can work it out.
