Question

another mole question show the working for me please i am not sure how to do this problem
the eqn. for photosynthesis.. if 100g of water react with excess oxygen, how many liters of oxygen will be produced? assume stp

Answer 1

i got 124.5 dm^3

Answer 2

Bio isn't exactly my best subject :/ can you show me the working for photosynthesis? I'll be able to help you then.

Answer 3

6CO2carbon dioxide + 6H2O water +light-> C6H12O6 glucose+ 6(O2) oxygen

Answer 4

the mole ratio would be re written as 1:1 right?

Answer 5

18 * 6 gm of h20 reacr to form 32 * 6 gm o2

then....100gm of water react to form hw many gm of o2?

Answer 6

6CO2+ 6H2O -> C6H12O6 + 6O2

Mol H2O = 100/18
= 5.56

6 Mol H2O -> 6 Mol O2

5.56 mol H2O -> 1* 5.56 mol O2
= 5.56 mol O2

5.56*22.4= 124.544 dm^3

Answer 7

@Roku : yeah, the mol ratio would be written as that when you compare (:

Answer 8

32 * 6 / 18 * 6 * 100

= 177.78 gm.

Answer 9

Then you just convert it into litre! I forgot about that :/

Answer 10

22.4 L = 1 mole

Moles = 177.78 /32 = 5.5

So........ 22.4 * 5.55 = 124.544 L

Answer 11

thanks guys

Answer 12

Welcome....)

Answer 13

yahoo i dont really understand your way completely

Answer 14

so it would be 124544cm^3 ??

Answer 15

^ yeah.
