Question

Measuring Volume

For each of the 3 graduated cylinders, do the following procedure.

Determine the value of each increment in milliliters. Fill each roughly 1/2 way, which I fill them at exactly halfway, 50ml, 25ml, and 5 ml.
Read and record the volume in milliliters for each of the three graduated cylinders. Record the volume from the bottom of the meniscus.
a. 100 ml graduated cylinder (to nearest 0.1 ml)
b. 50 ml graduated cylinder (to nearest 0.1 ml)
c. 10 ml graduated cylinder (to nearest 0.05 ml)

Estimate Fill one of your test tube to the top and estimate the volume of liquid. Do not measure just estimate.

100 ml graduated cylinder: ____________
50 ml graduated cylinder: ____________
10 ml graduated cylinder: ____________
Full test tube estimate: ____________

Answer 1

When measuring the volume of liquid in a graduated cylinder, it is important to read it at the bottom of the meniscus and make an estimate based on the closest mark. The level of precision depends on the graduations on the cylinder. In this experiment, you will need to record the volume in milliliters for each graduated cylinder, including a 100 ml cylinder to the nearest 0.1 ml, a 50 ml cylinder to the nearest 0.1 ml, and a 10 ml cylinder to the nearest 0.05 ml.

Step-by-step explanation:

When measuring the volume of liquid in a graduated cylinder, it is important to read it at the bottom of the meniscus, which is the curved surface of the liquid. To determine the volume, you need to mentally subdivide the distance between the markings and make an estimate based on the closest mark.

For example, in a 100 ml graduated cylinder, if the meniscus appears to be closer to the 20 ml mark, the estimated volume would be 19.9 ml. The level of precision depends on the graduations on the cylinder, with 1 ml graduations allowing measurements to the nearest 0.1 ml.

In this experiment, you will need to record the volume in milliliters for each graduated cylinder, including a 100 ml cylinder to the nearest 0.1 ml, a 50 ml cylinder to the nearest 0.1 ml, and a 10 ml cylinder to the nearest 0.05 ml.
