Transcribed Image Text:**Determining the Molecular Formula of Compound X**
In this problem, you are given information about the combustion of a compound known as Compound X, which is composed of carbon, hydrogen, and possibly oxygen. The compound has a molecular molar mass of 26 g/mol. When 4.00 g of Compound X is burned completely in excess oxygen, the masses of the resulting products are carefully measured, as shown in the table below.
| **Product** | **Mass** |
|----------------------|-----------|
| Carbon dioxide (CO₂) | 13.54 g |
| Water (H₂O) | 2.77 g |
Using this information, your goal is to determine the molecular formula of Compound X.
1. **Determine the moles of carbon and hydrogen:**
- From the mass of carbon dioxide (CO₂), calculate the moles of carbon.
- From the mass of water (H₂O), calculate the moles of hydrogen atoms.
2. **Consider the potential presence of oxygen:**
- If Compound X contains oxygen, evaluate its contribution by comparing the total mass of the products to the mass of Compound X.
3. **Calculate the empirical formula:**
- Combine the ratios of moles of each element to find the simplest whole number ratio.
4. **Determine the molecular formula:**
- Use the given molecular molar mass (26 g/mol) to convert the empirical formula to the molecular formula.
You can enter your findings into the provided input box to finalize your answer.
(Note: The molecular formula should be expressed in terms of the subscripts of the elements, indicating the quantity of each element in a molecule of Compound X.)
