how many moles of o2 are needed to react with 24 moles of c2h6? 2c2h6 + 7o2 → 4co2 + 6h2o 24 moles c2h6 | 7 moles o2 / 2 moles c2h6 = 168 / 2 moles o2 = ? moles o2
Answer
Explanation:
Step1: Identify mole - ratio
From the balanced equation $2C_{2}H_{6}+7O_{2}\rightarrow4CO_{2}+6H_{2}O$, the mole - ratio of $C_{2}H_{6}$ to $O_{2}$ is $2:7$.
Step2: Set up mole - conversion
We have 24 moles of $C_{2}H_{6}$. Using the mole - ratio, the number of moles of $O_{2}$ is calculated as $\frac{24\ moles\ C_{2}H_{6}\times7\ moles\ O_{2}}{2\ moles\ C_{2}H_{6}}$.
Step3: Calculate the result
$24\times\frac{7}{2}=84$ moles of $O_{2}$.
Answer:
84
