• kg/L - Kilograms per liter
• lb/ft³ - Pounds per cubic foot
• lb/gal - Pounds per gallon

Example: Water density = 1 g/mL = 1000 kg/m³ = 62.43 lb/ft³

4. Molality

Moles of solute per kilogram of solvent:

• mol/kg - Molal (standard)

Key Formulas

Molarity (M) Calculations:

Molarity (M) = moles of solute / liters of solution

Moles = Molarity × Volume (L)

Mass (g) = Moles × Molar Mass (g/mol)

Dilution Formula:

M₁V₁ = M₂V₂

Where: M₁ = initial concentration, V₁ = initial volume, M₂ = final concentration, V₂ = final volume

Percent Concentration:

% w/v = (mass of solute in g / volume of solution in mL) × 100

% w/w = (mass of solute / mass of solution) × 100

Density Relationship:

Density = Mass / Volume

Mass = Density × Volume

PPM/PPB Conversions:

1 ppm = 1 mg/L (for aqueous solutions)

1 ppb = 1 μg/L = 0.001 ppm

Tips & Best Practices

Accuracy Tips:

• Significant Figures: Maintain appropriate precision for your application
• Temperature: Remember that density and concentration can vary with temperature
• Purity: Account for reagent purity when calculating masses
• Hydration: Consider water of crystallization in salts

Common Conversions to Remember:

• 1 M = 1000 mM = 1,000,000 μM
• 1 g/mL = 1 kg/L = 1000 kg/m³
• 1 ppm ≈ 1 mg/L (in water)
• 1% w/v = 10 g/L = 10 mg/mL

Safety Reminders:

• Always double-check calculations for hazardous chemicals
• Verify units match your laboratory protocols
• Use appropriate safety equipment when handling concentrated solutions
• Label all solutions with concentration and date

Frequently Asked Questions

Q: What's the difference between molarity and molality?

A: Molarity (M) is moles per liter of solution, while molality (m) is moles per kilogram of solvent. Molality doesn't change with temperature.

Q: How do I convert between % w/v and molarity?

A: First convert % w/v to g/L (multiply by 10), then divide by molar mass to get molarity. Example: 5% w/v = 50 g/L ÷ molar mass.

Q: Is g/mL the same as g/cm³?

A: Yes! 1 mL = 1 cm³, so these units are identical.

Q: What is a Dalton (Da)?

A: A Dalton is approximately equal to the mass of one hydrogen atom (1.66 × 10⁻²⁴ g). It's commonly used for molecular weights of proteins.

Q: How accurate are the conversions?

A: The converter uses precise conversion factors and displays results to 6 decimal places for scientific accuracy.

Q: Can I convert between different types of concentrations?

A: Direct conversion between some units (like M to % w/v) requires knowing the molar mass. The converter handles standard unit conversions within each category.
