For 2.05 mol C2H6:
What is the mole ratio between C2H6 and O2 in the balanced equation?
2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g)
X = _______mol O2
Y = ________mol C2H6
Now, consider the following unbalanced equation:
C2H6(g) + O2(g) → CO2(g) + H2O(g)
Which amount requires more oxygen gas, 2.05 mol C2H6 or 29.3 g C2H6?
