All Conversions Part II | Atoms → Moles → Mass → Volume | Full Mole Map Explained
In this lesson from the MathSupport channel (@mathsupportnow), we continue exploring every major mole‑based conversion pathway using the full conversion map: particles ↔ moles ↔ molar mass ↔ mass ↔ molar volume ↔ volume. You’ll learn how to move between atoms, molecules, grams, liters, and moles using Avogadro’s number and the molar volume at STP. Each example is solved step‑by‑step with full unit cancellation, just like in class.

What You’ll Learn in This Video:
✅ The Complete Conversion Map
Particles → moles → mass

Mass → moles → volume
Volume → moles → particles
Using Avogadro’s number (6.02 × 10 ^ 23)
Using molar volume at STP (22.4 L/mol)
How to structure dimensional‑analysis chains correctly

✅ Example 1: Counting Atoms in a Hydrate
Copper(II) sulfate pentahydrate
Breaking down atoms per molecule
Scaling to multiple molecules
Final: 84 atoms in 4 molecules

✅ Example 2: Mass of 125 Helium Atoms
Atoms → moles → grams
Using Avogadro’s number and molar mass
Final mass: 8.3 × 10 ^ (−22) g

✅ Example 3: Mass of 3.45 mL of O₂ at STP
Converting mL → L L → moles using 22.4 L/mol , Moles → grams using molar mass

✅ Example 4: Atoms in 1 Mole of NH₄Cl
Mole → molecules → atoms : Counting atoms inside the compound


✅ Example 5: Volume of 16.5 g of AsH₃ at STP
Mass → moles → liters
Using molar mass 77.9 g/mol
Final volume: 4.74 L

✅ Example 6: Volume of Molecules of SO₂
Molecules → moles → liters
Using Avogadro’s number and molar volume :Final volume: 0.322 L (3 sig figs)
