🧪 What is Density? Density is a measure of how much mass is packed into a given volume. --- 🔍 Definition: > Density = Mass / Volume Mass is how much matter something contains (measured in grams, kg, etc.). Volume is how much space it takes up (measured in cm³, mL, L, etc.). --- 🧮 Formula: Density = Mass/Volume Unit of density (in SI): kilograms per cubic meter (kg/m³) In labs or daily use: grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL) --- 🧊 Example: If a block of metal ha
