Liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . suppose 10.3 g of octane is mixed with 69. g of oxygen. calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. round your answer to significant digits.

Explanation:

We are given the masses of two reactants and asked to determine the mass of the product.

This looks like a limiting reactant problem.

1. Assemble the information

We will need a balanced equation with masses and molar masses, so let’s gather all the information in one place.  

MM:         114.23     32.00      44.01

               2C₈H₁₈ + 25O₂ ⟶ 16CO₂ + 18H₂O

Mass/g:     10.3        69.  

2. Calculate the moles of each reactant

3. Calculate the moles of CO₂ from each reactant

4. Calculate the mass of CO₂
