Hi, we did a small respiration task in class and now I need to calculate a few things.

I placed a bottle of NaOH in another bottle, together with a bottle of yeast and glucose. I did the same with another bottle, but without the yeast/glucose. Amount of glucose 0.2g.

Now I need to calculate how much CO₂ has been produced and how much maximum can be produced.

I also need to know if there was enough O₂ in the bottle to let the glucose react completly (bottle is 440ml). And if there wasn't to much CO₂ in the bottle which gives a false result.

I also needed to know how much NaOH has been used.

What I have so far:
Titer of NaOH of bottle yeast/glucose: 0.089N
Titer of NaOH whithout yeast/glucose: 0.071N
NaOH used: 0.089N - 0.071N = 0.027N

Reaction of glucose with O₂
C₆H₁₂O₆+O₂->6CO₂+4H₂O

I'm not sure if those are right

Thanks

Not checking anything else - the reaction equation is not properly balanced.

C₆H₁₂O₆ + 6 O₂ ->6 CO₂ + 6 H₂O

I'm really not good at this, but is this one right?

perfect!
