which glassware produces the best precision in measuring 10mL of a liquid
Homework Answers
Burets : A buret is a long, narrow tube with a stopcock at its base. It is used for accurately dispensing variable volumes of liquids or solutions. It is graduated in 0.1 mL increments, with the 0.00 mL mark at the top and the 50.00 mL mark near the bottom. Notice that the marks do not go all the way to the stopcock. Therefore the buret actually will hold more than 50.00 mL of solution. Burets with liquid capacities of 25.00 mL and 10.00 mL are also available.
Pipets : Pipets are designed to deliver a known volume of a liquid. Their volumes range from less than 1 mL to about 100 mL. There are several types, which vary in accuracy and in the type of task for which they are optimum.

Are the ones answered also correct?
The precision of a measuring device is given by the difference between two consecutive indicated measurements. In other words, how far apart are the closest indicated values or markings. For example, there are tick marks every millimeter on the ruler. At times, a measurement can be estimated to a smaller difference, but the precision of the device is determined just from the indicated values. What is the precision of the ruler? What is the...

Accuracy and Precision. Trooper Watkins uses a measuring wheel (image at right) to measure the distances involved in traffic accidents. One rotation of the wheel is supposed to be 36 inches, but it is really only 35 7/8 inches. Trooper Watkins’ new digital measuring wheel has an LED that gives reading to a tenth of an inch. His old mechanical measuring wheel, which was also supposed to be 36” in circumference, was really 36 1/4”. Its analog readout showed measurements...

no Design a simple experiment to determine which type of volumetric glassware is the most accurate and the most precise at delivering a given volume. Your experiment must incorporate the following materials: analytical balance, distilled water, and a separate beaker used for mass measurements. Hint: Design your experiment around a physical property of water. (3) Be sure to explain which calculations you will perform in your experiment to determine accuracy and precision. (2)
