Key Formulas

1. Density

$\rho = \frac{m}{V}$

• Variables:
  • ( \rho ): Density (g/cm³)
  • ( m ): Mass (g)
  • ( V ): Volume (cm³)
• Application: Determine material properties, e.g., in quality control.
• Example: 50 g of a liquid occupies 25 cm³. Density = ( \frac{50}{25} = 2 ) g/cm³.

2. Percent Composition

$\% = \frac{\text{Mass of Element}}{\text{Total Mass}} \times 100$

• Application: Analyze compound compositions.
• Example: In H₂O (18 g/mol), %H = ( \frac{2 \times 1}{18} \times 100 \approx 11.1% ).

3. Molar Mass

$M = \sum \text{(Atomic Masses)}$

• Application: Calculate moles for reactions.
• Example: Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol.

4. Ideal Gas Law

$PV = nRT$

• Application: Predict gas behavior.
• Example: Volume of 1 mole of gas at 1 atm, 273 K = ( \frac{1 \times 0.0821 \times 273}{1} \approx 22.4 ) L.

Usage Tips

• Organize by Topic: Group formulas for easy access.
• Memorize Units: Ensure correct units for calculations.
• Practice Problems: Apply each formula to reinforce understanding.

Real-World Applications

• Engineering: Density for material selection.
• Environmental Science: Gas laws for air quality analysis.
• Pharmacy: Molar mass for drug formulation.
