How do I solve this 

**Calculate the Mass Percent of H in \( \text{C}_3\text{H}_8\text{O} \).**

[Input Box] \(\%\)

**Explanation:**  
To find the mass percent of hydrogen (H) in the compound \( \text{C}_3\text{H}_8\text{O} \), follow these steps:

1. **Determine the Molar Mass:**
    - Carbon (C): 12.01 g/mol
    - Hydrogen (H): 1.01 g/mol
    - Oxygen (O): 16.00 g/mol

   Calculate the total molar mass:  
   \((3 \times 12.01) + (8 \times 1.01) + (1 \times 16.00) = \text{Molar mass of } \text{C}_3\text{H}_8\text{O}\).

2. **Calculate the Mass Percent of Hydrogen:**
   - Find the total mass of hydrogen atoms: \(8 \times 1.01\).
   - Use the formula:  
     \[
     \text{Mass percent of H} = \left( \frac{\text{Total mass of H}}{\text{Molar mass of } \text{C}_3\text{H}_8\text{O}} \right) \times 100\%
     \]

3. **Input the Result:** 
   Enter the calculated mass percent value in the provided input box.
