for 15.39 b, why does the solutions manual have ".37[a] initial as part of the solution. Where is the .37 coming from?

Hi friend!

So the 0.37 is actually for part a, it just is lined up weirdly in the solutions manual so it looks like its part of part b.

Hope this helps

Hi, that is actually for part b and 0.37[A]initial comes from finding the moles total moles of A with the information give about concentration B.
Because A--> 2B + C so, [A]total= [A]initial-([B]x([A]/2[B])) to give you 0.055(mol A)/L which is equivalent to 0.37[A]initial

I hope that was helpful
