how many moles of water will be formed if 8.9 moles of methane are burned? equation: ch₄ + o₂ → co₂ + h₂o conversion factor: 8.9 moles ch₄ | moles o₂ / moles ch₄
Answer
Explanation:
Step1: Balance the chemical equation
$$CH_4 + 2O_2\rightarrow CO_2+2H_2O$$
Step2: Determine the mole - ratio
The mole - ratio of $CH_4$ to $H_2O$ from the balanced equation is $1:2$.
Step3: Calculate moles of water
If we have 8.9 moles of $CH_4$, and the mole - ratio of $CH_4$ to $H_2O$ is $1:2$, then the moles of $H_2O$ formed is $n_{H_2O}=8.9\times2$. $n_{H_2O} = 17.8$ moles
Answer:
17.8 moles
