What is the mass, in mg\text{mg}mg, of carbon formed when 3.5 × 10-4 mol of hexane undergoes incomplete combustion according to the equation below?

2C6H14(l)+7O2(g)→12C(s)+14H2O(g) 2\text{C}_6\text{H}_{14}(\text{l}) + 7\text{O}_2(\text{g}) \rightarrow 12\text{C}(\text{s}) + 14\text{H}_2\text{O}(\text{g}) 2C6​H14​(l)+7O2​(g)→12C(s)+14H2​O(g)

(Use Ar(C)=12.0A_r(\text{C}) = 12.0Ar​(C)=12.0)
