a) #3/5#

b) #4/5 #

Explanation:

a) Using the mole ratio from the equation, #5# mols of #"O"_2# will produce #3# mols of #"CO"_2#. Therefore, the ratio of #"O"_2# used to #"CO"_2# produced will be #1:3/5#.

b) The same concept as in the previous question. #5# mols of #"O"_2# will produce #4# mols of #"H"_2"O"#. Therefore, the ratio of #"O"_2# used to #"H"_2"O"# produced is #1:4/5#.
