### Chemistry Problem: Molecule Calculation

**Question:**

3) How many molecules are in 120.6 g of carbon? Show all your work.

**Instructions:** To solve this problem, consider the following steps:

1. **Determine the number of moles of carbon:**
   - Use the molar mass of carbon, which is approximately 12.01 g/mol.
   - Calculate the moles using the formula:
     \[
     \text{Moles of Carbon} = \frac{\text{Mass of Carbon (g)}}{\text{Molar Mass of Carbon (g/mol)}}
     \]

2. **Calculate the number of molecules:**
   - Use Avogadro's number, \(6.022 \times 10^{23}\) molecules/mol, to convert moles to molecules.
   - Multiply the number of moles by Avogadro's number.

3. **Show all calculations clearly to ensure understanding and accuracy.**
