Solutions Cheatsheet

Cheat Codes & Shortcuts

  • Solution: Homogeneous mixture of solute(s) in solvent.
  • Solute: Substance dissolved in solvent.
  • Solvent: Substance in greatest amount, does the dissolving.
  • Molarity (\( M \)): Moles of solute/liter of solution.
  • Molality (\( m \)): Moles of solute/kg of solvent.
  • Normality (\( N \)): Equivalents of solute/liter of solution.
  • Mass %: \( \frac{\text{Mass of solute}}{\text{Mass of solution}} \times 100 \)
  • ppm: Parts per million.
  • Henry’s Law: \( p = k_H x \) – gas solubility proportional to partial pressure.
  • Raoult’s Law: Vapor pressure lowering relates to solute mole fraction.

Quick Reference Table

Term Formula / Description Example / Note
Molarity \( M = \frac{\text{moles of solute}}{\text{volume of solution in L}} \) 1M NaCl: 1 mole NaCl in 1L solution
Molality \( m = \frac{\text{moles of solute}}{\text{kg of solvent}} \) 1m NaCl: 1 mole NaCl in 1kg solvent
Mass % \( \frac{\text{mass of solute}}{\text{mass of solution}} \times 100 \) 10g NaCl in 90g H2O = 10%
ppm \( \frac{\text{mass of solute}}{\text{mass of solution}} \times 10^6 \) 1 ppm = 1mg/L water
Raoult's Law \( p_{solvent} = p^0_{solvent} x_{solvent} \) Lowering vapor pressure in solution
Henry's Law \( p = k_H x \) Solubility of CO2 in soda

Advice

Step 1: Choose the concentration unit: molarity, molality, % or ppm.

Step 2: Always use proper units (L for molarity, kg for molality).

Step 3: For gases, use Henry’s Law to relate pressure and solubility.

Step 4: Raoult’s Law helps find vapor pressure and freezing/boiling point change.

Step 5: For dilution: \( M_1 V_1 = M_2 V_2 \).

Solutions Quick Tips

  • Convert: g to mol using molar mass, mL to L dividing by 1,000.
  • For dilute solutions: Molarity ≈ molality.
  • Raoult’s Law: Applies best to ideal solutions.
  • Henry’s Law: Higher pressure increases gas solubility in liquid.
  • Dilution: Use \( M_1 V_1 = M_2 V_2 \) for mixing.
