Which piece of glassware is the most accurate?
a. Erlenmeyer
b. Accuracy depends on the scientist, not the glassware
c. Beaker
d. Graduated Cylinder
There are 5 types of glassware which are used to measure out specific volumes among them graduated cylinder is one of them. So option d is correct.
Which piece of glassware is the most accurate? a. Erlenmeyer b. Accuracy depends on the scientist, not the glassware c....
What piece of glassware would a student use to deliver 4.00mL of solution? A. 25 mL volumetric flask B. 10 mL beaker C. 5mL Erlenmeyer flask D. 25mL graduated cylinder E. 10mL volumetric pipet
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)
Which piece of glassware has the smallest diameter and which has the largest diameter among10 volumetric flask,25 volumetric flask, 10ml graduated cylinder, 25 mL graduated cylinder, 10 mL volumetric pipette, 1 mL volumetric pipette and 1 mL graduated pipette at the level of meniscus?
1. What do volumetric glassware measure? What types of volumetric glassware will you be using in this experiment? 2. What is density? How is it calculated? 3.Define meniscus. State how you use the meniscus in making volumetric measurements. Draw a sketch of a meniscus for water in a graduated cylinder. 4. Define accuracy and precision. Explain what the “reliability of a measurement” means. (These concepts can be found in Chapter 1 of your text.) 5. Why will you calculate accurate...
