Question

How many moles of CO2 are produced

when 10.0 moles of C3H8 are burned in
excess oxygen?
C3H8 + 5 O2 ---> 3 CO2 + 4H2O

Answer 1

30.0 mol CO₂

Step-by-step explanation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

To answer this problem we need to convert moles of C₃H₈ into moles of CO₂: We'll do that by using the stoichiometric coefficients, using a conversion factor that has C₃H₈ moles in the denominator and CO₂ moles in the numerator:

10.0 mol C₃H₈ *
`(3molCO_2)/(1molC_3H_8)` = 30.0 mol CO₂
