Web5 jan. 2024 · All burette readings are given to an accuracy of 0.05 mL. Make sure your eye is at the same level of the meniscus to avoid an error. For water and most liquids, the meniscus is concave or like a U shape. Read the center of the meniscus or the bottom of the U-shape. Figure: How to read the meniscus. The correct reading is 19.50 mL. WebCommercially available burets can usually be read with an accuracy of → ± 0.01 ml. Probably the most familiar application of a buret is in the process known as titration, …

Webneeds to be below zero mark on buret before starting titration. 3. Record the initial volume of KMnO 4 to the correct number of significant figures. 4. Place 1.00 mL of the hydrogen peroxide solution into a 250 mL Erlenmeyer flask. 5. Add about 25 mL of distilled water to the flask. 6. Place 5.0 mL of 6 M H 2 SO 4 into the flask. 7. WebJust remember that densities of gases are reported in g/L NOT g/mL. What is the approximate molar mass of air expressed in g/L? List 3 gases that float in air: List 3 gases that sink in air: Exercise 16 Gas Density/Molar Mass The density of a gas was measured at 1 atm and 27ºC and found to be 1 g/L. Calculate the molar mass of the gas. WebA semi-micro burette is a burette that has a volume capacity of about 25 mL and the smallest scale of uncertainty or estimation that can be read is 0.050 mL.
