This MayeleCalc guide explains the concept in plain language so you can use the related calculator with better context and confidence. Work through each section, review the practical example, and check the common mistakes before applying the result.
Molarity describes amount per volume
Molarity is moles of solute divided by litres of solution. Convert mass to moles using molar mass when necessary.
Dilution conserves solute
The equation C₁V₁ = C₂V₂ assumes the amount of solute remains constant while solvent changes total volume.
Volumes need matching units
Both volumes may be in millilitres or both in litres because their ratio matters. Mixing units without conversion creates large errors.
Calculation is not a safety procedure
Preparation requires suitable equipment, labels, protective equipment, and substance-specific procedures. Follow approved protocols.
Practical example
See the idea in action
Write concentration in moles per litre before calculating. For [H⁺] = 0.0001 mol/L, pH = −log₁₀(0.0001) = 4.
Common mistakes to avoid
- ×Entering a concentration in the wrong unit
- ×Forgetting that pH is logarithmic
- ×Rounding scientific notation before completing the equation
Key takeaways
- ✓Units must match the formula
- ✓A one-unit pH change represents a tenfold concentration change
- ✓Record both the input precision and final result
