Problem 11.33

I can sort of see how the value 6.9 was calculated, but I'm having a little trouble understanding why the top values are something like 1.0x10^-4 instead of the given value 0.1 mmol. Is there a specific unit being used for this generally? Hope that made sense.

Concept explanation

I'm having trouble understanding this concept dealing with reaction quotients.
For example in #13 of the Ch. 11 problems, the reaction quotient is (1)/(BCl3)^2 instead of (B2Cl4)(Hg2Cl2)/(Hg)^2 (BCl3)^2 . How did it reduce to that? The same happens in part b and other problems.

Problem 11.7 (part a)

small question: I'm confused on how you can tell that the third flask is at equilibrium but not the other ones is all.
could someone explain?

Re: Molar Mass

If i'm not mistaken, molar mass is just grams per mole while molarity is number of particles in a liter (moles per liter). And then as for the molar weight vs. molar mass, it is the same value just different units like said above :)
