🧪 Practical Example
Example: Convert 3 moles of NaCl (table salt) to grams.
- Step 1: Number of moles = 3
- Step 2: Molar mass of NaCl = 58.44 g/mol
- Step 3: Apply formula → Grams = Moles × Molar Mass
- Step 4: 3 × 58.44 = 175.32 g
Result: 3 moles of NaCl = 175.32 grams
The calculator displays:
- Number of moles: 3 mol
- Molar mass: 58.44 g/mol
- Compound: NaCl
- Formula: grams = moles × molar mass
- Calculation steps: 3 × 58.44 = 175.32 g
