Answer to Question #95608 in Physical Chemistry for m

Question

the combustion of ethane (C2H6) produces carbon dioxide and steam. How many moles of CO2 are produced when 5.65 mil of ethane is burned in an excess of oxygen?

Answer 1

$Reaction\ is\\2C_2H_6(g) + 7O_2(g) → 4CO_2(g) + 6H_2O(l)\\$

2 moles ethane produces 4 moles of Carbon dioxide

So $5.65$ moles of ethane will produce $\frac{4}{2}\times 5.645=11.3\ moles\ CO_2$
