How many moles of \( \mathrm{CO}_{2} \) are produced when 2 moles of \( \mathrm{C}_{3} \mathrm{H}_{8} \) react with excess \( \mathrm{O}_{2} \) in the following reaction? \( \mathrm{C}_{3} \mathrm{H}_{8}+5 \mathrm{O}_{2} \rightarrow 3 \mathrm{CO}_{2}+4 \mathrm{H}_{2} \mathrm{O} \)

A 2 moles

B 6 moles

C 10 moles
