Question

Consider the reaction below.


2C6H14 + 19O2 mc032-1.jpg 12CO2 + 14H2O


How many moles of hexane (C6H14) must burn to form 18.4 mol of carbon dioxide?


1.53 mol

3.07 mol

110. mol

175. mol
Rx shows a 2 to 12 Hexane to CO2 ratio, or (if reduced) a 1 to 6 mole Hexane:CO2 ratio; that is, for each mole of hexane burned, 6 moles of CO2 are produced. So, if given 18.4 moles Hexane then... 6 times more in moles of CO2 will be formed. = 110 moles.
