For the reaction: C2H6 +
02 → CO2 +
H20
How many grams of CO2 are produced for each 8.00 grams of H20 produced?

Explanation:

no of moles of water=8.00/18=0.4

1 mole of C2H6 produced 1 mole of CO2 and 1 mole of H2O

so  for 1 mole of H2O 1 mole of CO2 is produced therefore for 0.4 mole of H2O 0.4 mole of CO2  is produced

now 0.4 mole of CO2 contain how much grams=0.4*44=17.6grams

but complete combustion of 2 mole of ethane produce 4 mole of CO2 and 6 moles of H2O

so  for 6 mole of H2O 4 mole of CO2 is produced therefore  for 0.4 moles of H2O 0.27 moles of CO2 is produced

the answer is 303.15 or 303
