is this right
« on: March 08, 2008, 01:24:48 PM »
ok here is another homework question, i think i worked it out but am not compeletly  sure can some one take a look at it and let me know:


q:  6CO2 + 6H2O -----> C6H12O6 +6O2
                                 glucose

if a tree produces 100g of glucose in a day, how many grams of Carbon Dioxide is it using up and how many grams of oxygen is it producing in that time? show calculation.

My answer

100g glucose in a day X 264g CO2/180g glucose = 146.66 g CO2

146.6g CO2 is OK, what about oxygen?

OK HERE IS OXYGEN

100g glucose X 96g06/180g glucose = 53.33g O2

I feel like you are throwing numbers in vague hope that you will hit the right spot.

What is mass of 6 moles of oxygen O2?

Dear Marebare;

Why are you asking the “identical” Question twice? :   "Lost?”

Have you “Lost?” yourself?
(The value of Oxygen is still NOT right!  Would you like to have another guess.)


Good Luck!

OK. So when 180 g of glucose is produced, 6 moles of O2, or 192 g of oxygen is produced (no idea why ARGOS++ thinks different). How much oxygen per 100 g of glucose?

Dear  Mr. Borek;

Sorry!,  -  I meant the Amount of Oxygen produced by the Three!


Good Luck!

Dear  Mr. Borek;

With all my due/proper Respect:   IMHO, I think, that you will find out by yourself (with time).

Kind regards!
