If 10g O2 and 200g C12H24 are ignited, what volume of CO2 gas can be produced at STP?

We need a stoichiometric equation....however, conditions of incomplete combustion apply...

Explanation:

#C_12H_24(l) + 18O_2(g) rarr 12CO_2(g) + 12H_2O(l)#

#"Moles of diesel"=(200*g)/(168.32*g*mol^-1)=1.19*mol#

#"Moles of dioxygen"=(10*g)/(32.00*g*mol^-1)=0.312*mol#

CLEARLY, there is insufficient dioxygen gas for complete oxidation. The product mix would likely contain quantities of particulate soot, and carbon monoxide, the products of incomplete combustion.

The question is unreasonable.
