How many moles of oxygen gas react to yield 0.200 mole water? . . C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
Harlamova29_29 [7]
C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g) 
molar ratio of H2O to O = 6:8 
<span>we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2 

Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.


I hope my answer has come to your help. Thank you for posting your question here in Brainly.
