You'd need

Start with the balanced chemical eqaution for your reaction, which is known as the **Sabatier reaction**

Notice that you have a **4 times more** moles of hydrogen gas.

Assuming both gases are *under the same conditions for pressure and temperature*, the mole ratio will become a *volume ratio*, i.e. regardless of haw many cubic meters of **4 times more** cubic meters of hydrogen for the reaction to take place.

Since you know how many cubic meters of hydrogen you have, you can use the volume ratio to determine how many cubic meters of

To determine how many cubic meters of methane you'd produce, use the fact that **1 mole**, or **1 cubic meter**, of **1 cubic meter** of

This means that you'd get
