# Measurement Instruments The document describes measuring instruments for mass and volume. ## Mass Measurement **1. Definitions:** * **Mass:** The amount of matter in an object. * **Units:** Gram (g) or Kilogram (kg) **2. Instruments for Measuring Mass:** * **Balance:** A balance is used to measure mass. ## Volume Measurement **1. Definitions:** * **Volume:** The space occupied by an object. * **Units:** Cubic centimeter (cm³) for solids, milliliter (mL) or liter (L) for liquids. **2. Instruments for Measuring Volume:** * **Graduated cylinder:** A graduated cylinder is used to measure the volume of liquids. * The volume is read at the bottom of the meniscus (the curved surface of the liquid). **Example:** In the example, the volume of liquid is read as 0.7 mL.
