Question

Plants produce sugar by photosynthesis using the reaction:
6CO2 (g) + 6 H2O (l) → C6H12O6 (s) + 6 O2 (g)
a) How many litres of pure carbon dioxide are required by a green plant in order to produce 450.0 g of
glucose, C6H12O6 (s) ?
b) How many litres of air are needed to supply the required CO2 in part (a), assuming that air is
0.0400% carbon dioxide by volume?

Answer 1

I got the answer to part a. I do not know how to do part b. Please explain.

Answer 2

This stoichiometry?

Answer 3

yes it is.

Answer 4

Goddarnit.

Answer 5

Can you show me how you do your work for part b

Answer 6

I have no idea.

Answer 7

No idea...

Answer 8

b) \(\sf \large L_{CO_2}=L_{air}*0.04\% \rightarrow L_{air}=\dfrac{L_{CO_2}}{0.0004}\)
