How many moles of O2 are needed to react with 2.55 mol of C2H2?
Lelechka [254]

Answer: 6.38 moles of O_2 are needed to react with 2.55 mol of C_2H_2

Explanation:

The balanced chemical reaction for the combustion of ethyne is:

2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

According to stoichiometry:

2 moles of C_2H_2 require = 5 moles of O_2

Thus 2.55 mol of C_2H_2 require = \frac{5}{2}\times 2.55=6.38 moles of O_2

Thus 6.38 moles of O_2 are needed to react with 2.55 mol of C_2H_2
