Let's calculate the **Formula Mass** (in atomic mass units, amu) and **Molar Mass** (in grams per mole, g/mol) for the compounds listed in the table:

1. **Calcium Carbonate (CaCO₃)**:
   - Atomic weights: Ca = 40.08 amu, C = 12.01 amu, O = 16.00 amu
   - **Formula Mass** = 40.08 + 12.01 + (3 × 16.00) = **100.09 amu**
   - **Molar Mass** = **100.09 g/mol**

2. **Aluminum Sulfate [Al₂(SO₄)₃]**:
   - Atomic weights: Al = 26.98 amu, S = 32.07 amu, O = 16.00 amu
   - **Formula Mass** = (2 × 26.98) + (3 × 32.07) + (12 × 16.00) = **342.17 amu**
   - **Molar Mass** = **342.17 g/mol**

3. **Sulfuric Acid (H₂SO₄)**:
   - Atomic weights: H = 1.008 amu, S = 32.07 amu, O = 16.00 amu
   - **Formula Mass** = (2 × 1.008) + 32.07 + (4 × 16.00) = **98.08 amu**
   - **Molar Mass** = **98.08 g/mol**

4. **Potassium Permanganate (KMnO₄)**:
   - Atomic weights: K = 39.10 amu, Mn = 54.94 amu, O = 16.00 amu
   - **Formula Mass** = 39.10 + 54.94 + (4 × 16.00) = **158.04 amu**
   - **Molar Mass** = **158.04 g/mol**

Here’s the filled table:

| Compound        | Formula Mass (amu) | Molar Mass (g/mol) |
|-----------------|--------------------|--------------------|
| CaCO₃           | 100.09              | 100.09             |
| Al₂(SO₄)₃       | 342.17              | 342.17             |
| H₂SO₄           | 98.08               | 98.08              |
| KMnO₄           | 158.04              | 158.04             |
