Question

Calculate the mass of carbon dioxide produced from complete combustion of 16.6 g of octane, C8H18, in the following reaction. C8H18 O2 --> CO2 H2O (unbalanced)

A. 51.2 g CO2
B. 102 g CO2
C. 57.6 g CO2
D. 0.799 g CO2
E. 1.163 g CO2

Answer 1

51.2g of CO2

Step-by-step explanation:

The first step is to balance the reaction equation as shown in the solution attached. Without balancing the reaction equation, one can never obtain the correct answer! Then obtain the masses of octane reacted and carbon dioxide produced from the stoichiometric equation. After that, we now compare it with what is given as shown in the image attached.
