## Why is Molecular Weight Important?
Molecular weight, or molecular mass, of a compound, is the sum of the atomic weights of all atoms in a molecule. It is crucial for:
1. **Stoichiometric Calculations**: Accurate measurements in chemical reactions.
2. **Determining Physical Properties**: Such as boiling and melting points.
3. **Pharmaceutical Applications**: Dosing and drug formulation.
## What is the Molecular Formula of 9-Fluorenol?
The molecular formula for 9-fluorenol is C13H10O. This indicates that each molecule consists of 13 carbon atoms, 10 hydrogen atoms, and one oxygen atom.
## How to Calculate the Molecular Weight?
To calculate the molecular weight of 9-fluorenol:
1. **Identify Atomic Weights**: From the Periodic Table, we get:
- Carbon (C): 12.01 u.
- Hydrogen (H): 1.01 u.
- Oxygen (O): 16.00 u.
2. **Multiply by Quantity**:
- Carbon: 12.01 u * 13 = 156.13 u.
- Hydrogen: 1.01 u * 10 = 10.10 u.
- Oxygen: 16.00 u * 1 = 16.00 u.
3. **Sum Up the Values**: 156.13 u + 10.10 u + 16.00 u = 182.23 u.
Thus, the molecular weight of 9-fluorenol is approximately 182.23 atomic mass units (u).
