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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faa8d3fce-d16d-4f4d-b492-1dee716a707b%2F8f911a15-7039-4f86-9161-b7e459d54470%2Fb5gspyb_processed.jpeg&w=3840&q=75)
