Problem 68

Quantitative Information from Balanced Equations (Section) The complete combustion of octane, C8H18, a component of gasoline, proceeds as follows: 2 C8H18(/) + 25 O2(g)—»16 C2(g) + 18 H2O(g) (a) How many moles of O2 are needed to burn 1.50 mol of C8H18? (b) How many grams of O2 are needed to burn 10.0 g of C8H18? (c) Octane has a density of 0.692 g/ml at 20 °C. How many grams of 02 are required to burn 15.0 gal of C8H18 (the capacity of an average fuel tank)? (d) How many grams of CO2 are produced when 15.0 gal of C8H18 are combusted?

Step 1 of 3

Chapter 9 from “Introductory Chemistry” by Zumdahl and Decoste, 7 /8 editionth Pg 203. INFORMATION GIVEN BY CHEMICAL EQUATIONS *Coefficient in a balanced equation give us the relevant number of molecules Note: we need to focus on the ratio of coefficients not the specific coefficients themselves Ex: The ratio of item when making a sandwich is: 2 bread slices + 3 meat slices + 1 cheese slice...
