15 paź 2022 · The volume of a liquid can be directly measured with specialized glassware, typically in units of milliliters (mL) or liters (L). In this lab, a beaker, two graduated cylinders and a burette will be used to measure liquid volumes, and their precision will be compared.
In this experiment, we will test how consistent the mass of 10 mL in a graduated cylinder is, and how close to the expected mass (at room temperature, the mass of 10 mL of distilled water is about 9.9820 grams).
Given the following graduated cylinders (calibrated in mL), determine the smallest scale division (that is, the value for the minor grids) and the smallest fractional part of the scale division that can be reasonably estimated.
How to precisely measure the volume of a liquid using a variety of volumetric instruments.
We use millilitres and litres to measure volume and capacity. Capacity is the amount of liquid a container can hold. Volume is how much liquid is in the container.
Use tap water to fill a 50-mL beaker to the 20-mL mark. Use a disposable plastic pipet to adjust the water level until the bottom of the meniscus is lined up as precisely as possible with the 20-mL line.
