# Instrument Description The image shows a diagram of various laboratory instruments, likely for measuring volume. The text accompanying the diagram details the instruments and considerations for accurate measurement. **Instruments:** * **Pipette:** Used for accurate measurement of fixed volumes. Example volume: 1.7, 10.0 cm³. * **Volumetric Flask:** Used for accurate measurement of fixed larger volumes. Example volume: 100 cm³. * **Measuring Cylinder:** Used to measure volumes within a specified range. Range of volumes up to the nearest 0.5 cm³. * **Burette:** Measures volumes with accuracy up to 0.05 cm³. Range of measurements is noted as (e.g. 31.55). * **Gas Syringe:** Measures gas volumes. Range up to 100 cm³. **Additional Notes:** * **Electronic Balance:** Used to measure mass with an accuracy of ±0.01 g. * **Beam Balance:** Accuracy varies depending on the markings on the balance. It requires attention to the markings to avoid errors. * **Meniscus:** The curved surface of a liquid in a measuring instrument. The text notes the importance of properly positioning the eyes to avoid parallax error. It also specifies that the meniscus should be read at eye level. (concave or convex and the position of the instrument). **Error Discussion:** The text suggests the importance of understanding and accounting for errors in measuring volume and mass. The notes highlight the accuracy of instruments and potential sources of error in measurements.
