Environmental Limits
Understanding Chemical Concentrations
Concentration Units
Molarity (M)
Moles of solute per liter of solution. Most common in chemistry.
Parts Per Million (ppm)
1 part solute per 1,000,000 parts solution. Common in environmental analysis.
Weight Percent (w/w%)
Weight of solute per 100 weight units of solution.
Key Relationships
PPM to mg/L
For dilute aqueous solutions: 1 ppm ≈ 1 mg/L
Molarity to PPM
PPM = Molarity × Molecular Weight × 1000
Percent to PPM
PPM = Percent × 10,000

Frequently Asked Questions
What's the difference between molarity and molality?
Molarity (M) is moles per liter of solution, while molality (m) is moles per kilogram of solvent. Molarity changes with temperature, molality doesn't.
How do I convert between PPM and percentage?
PPM to percentage: divide by 10,000. Percentage to PPM: multiply by 10,000. For example, 1% = 10,000 PPM.
Why do I need molecular weight for conversions?
Molecular weight is essential for converting between molar concentrations and mass-based units like PPM or mg/L.
