Answer to Question #104138 in General Chemistry for Jada

Question

Use the following equation:
C4H10O + 6 O2 + 4CO2 + 5H2O
How many moles of O2 are needed to make 36.7 mol of CO2?

Answer 1

From this reaction: C4H10O + 6 O2 = 4CO2 + 5H2O ,

a proportion can be made:

x/6=36.7/4 ;

Where x - moles of O₂, needed to make 36,7 moles of CO₂;

6 - stoichiometric value of O₂ in this reaction; 4 - stoichiometric value of CO₂;

x=(36.7*6)/4= 55.05

Answer: 55.05 moles of O₂ are needed to make 36.7 moles of CO₂
