Question

How many liters of carbon dioxide are produced when 2.0 moles of `CH_4` are burned at `STP`?

Answer 1

44.8L

Explanation:

Assuming combustion to be the reaction producing the `CO_2`, you need to first write the balanced equation. Then you can calculate how much `CO_2` 2.0 moles of methane would produce with complete reaction.

`CH_4 + 2O_2 → CO_2 + 2H_2O`

This shows us that one mole of methane produces one mole of carbon dioxide, so 2.0 moles will produce 2.0 moles. Convert the moles to liters with the STP factor of 22.4L/mole for gases.
