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

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
