Depends on the height of the mountain. At 2500km (7500ft) it might boil-albeit reluctantly-at 100 degrees Celsius, but higher up not so much.
Answer:
21.4 L
Explanation:
Given data:
Volume of carbon dioxide produced = ?
Volume of oxygen = 37.4 L
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
It is known that,
1 mole = 22.414 L
There are 7 moles of oxygen = 7×22.414 = 156.9 L
There are 4 moles of carbon dioxide = 4×22.414 = 89.66 L
Now we will compare:
O₂ : CO₂
156.9 : 89.66
37.4 : 89.66/156.9×37.4 = 21.4 L
So from 37.4 L of oxygen 21.4 L of carbon dioxide is produced.
