Question
**Combustion of Ethane (CH₃CH₃)**

Gaseous ethane (CH₃CH₃) will react with gaseous oxygen (O₂) to produce gaseous carbon dioxide (CO₂) and gaseous water (H₂O). Suppose 2.7 g of ethane is mixed with 4.74 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to 3 significant digits.

- Empty input box followed by "g."
- Checkbox square labeled "10"
- Buttons with symbols: a green check mark, a circular arrow (likely for resetting), and a question mark (probably for help).

To find the maximum mass of water produced, you would have to use stoichiometry, which involves the balanced chemical equation for the combustion of ethane and then using the given masses to find the limiting reagent. The limiting reagent will determine the amount of product (water, in this case) that can be formed.

Reminder for calculations:
1. Write the balanced chemical equation.
2. Determine the molar masses of the reactants and products.
3. Convert the given masses of reactants to moles.
4. Use stoichiometry to find the moles of water produced.
5. Convert the moles of water to grams.

**Example Calculation:**

(You would add an example calculation below, illustrating the above steps with detailed arithmetic to guide students through the process.)
