How many moles of co2 are emitted into the atmosphere when 25.6 g c8h18 is burned

When 25.6 g     is burned, the moles of  emitted into the atmosphere is 1.80 mol

Explanation:

The molar mass of octane is calculated as  8(12) +18(1) = 114 g/mol.

Where atomic mass of Carbon is C=12, and Hydrogen H=1.The sample contains 25.6 g of octane, Therefore

The combustion of octane can be written as:

The mole ratio can be represented as:

= 16:2 =  8:1.  

Hence, the quantity of carbon dioxide emitted is:

= 1.80 mol
