🔬 M20 to Molarity & Weight Calculator ⚗️
Prepare chemistry solutions easily! Calculate Molarity and Weight of Substance required for an M/20 solution.
📐 Chemistry Behind the Calculation
M/20 Solution means:
M/20 = 1 ÷ 20 M = 0.05 M
Molarity Formula:
M = Number of moles ÷ Volume (L)
Weight of Substance Formula:
Weight (g) = M × Molecular Weight × Volume (L)
Example Equation:
H₂SO₄ (aq) → 2H⁺ (aq) + SO₄²⁻ (aq)

❓ FAQs: M/20 to Molarity & Weight of Substance Calculator
❓ What does M/20 mean in chemistry?
M/20 represents one-twentieth molar concentration, i.e., 0.05 M solution.
❓ Is M/20 same for all substances?
No. Weight depends on molar mass, even though molarity remains constant ⚖️.
❓ Can this calculator be used for NEET & IIT-JEE?
Absolutely ✅. It follows standard NCERT & competitive exam formulas.
❓ How accurate is this calculator?
It provides 100% formula-based accuracy with no rounding bias 🔬.
❓ Can I use it for lab solution preparation?
Yes, but always verify with lab manuals before final preparation.
