Mmm, you can work this one out in your head by reversing it.
<span>12.5 = 50g/4 </span>
<span>1/4 = 1/2 * 1/2 </span>
<span>thus in 14.4 seconds there have been 2 times the half life. 14.4/2 = 7.2 </span>
<span>the half life is 7.2 seconds.</span>

<h3>Mass of CO₂ generated from the combustion : 14.277 kg</h3><h3>Further explanation</h3>
Mass Heptane : 0.348 x 17 = 5.916 kg
mass C in Heptane (MW=100.21 g/mol) :
Mass Nonane : 0.101 x 17 = 1.717 kg
mass C in Nonane (MW=128.2 g/mol) :
Mass Octane : 0.551 x 17 = 9.367 kg
mass C in Otane (MW=114.23 g/mol) :
Total mass produced :
4.959+1.446+7.872=14.277 kg
