Which of the following pieces of glassware would least precisely measure 25 mL?

Which of the following pieces of glassware would least precisely measure 25 mL?

To measure 25 mL of water you could use a beaker, or an erlenmeyer flask because these estimate to the 1’s place digit. This would not be an accurate measurement.

Which of the following pieces of laboratory glassware should be used to most accurately measure out a 25.00 mL sample of a solution *?

Explanation: In order to measure 25.00 ml sample of a solution it should be used a 25 mL graduated cylinder, as it is previously and properly calibrated. The other laboratory glassware, beaker and erlenmeyer, have graduations which are approximate, so they are used when exact volumes are not needed.

Which piece of glassware measures more accurately a 25 mL beaker or a 25 mL graduated cylinder?

Terms in this set (34) beaker or erlenmeyer flask are least accurate because they are in graduations of 25 or 50 mL and are not calibrated during manufacturing. graduated cylinder is more precise than beakers.

How do I measure 50 mL?

This measurement converter chart will help you figure out the liquid measurements called for.

1. 0.5 ml = ⅛ teaspoon.
2. 1 ml = ¼ teaspoon.
3. 2 ml = ½ teaspoon.
4. 5 ml = 1 teaspoon.
5. 15 ml = 1 tablespoon.
6. 25 ml = 2 tablespoons.
7. 50 ml = 2 fluid ounces = ¼ cup.
8. 75 ml = 3 fluid ounces = ⅓ cup.

What is the maximum precision offered by the 100 mL graduated cylinder?

Example: The markings on a 100mL graduated cylinder are every 1mL, so the volume can be measured to ±0.1mL.

What is the most precise graduated cylinder?

The volumetric flask offers the highest level of precision and accuracy in accordance with ASTM E288 and E694 standards governing laboratory glass volumetric flasks and laboratory glass volumetric apparatus. Graduated cylinders have several etched graduations in ml divisions specific to each cylinder’s capacity.

What is the accuracy of a 100 mL graduated cylinder?

This graduated cylinder has a capacity of 100 ml with graduations marked every 1.0 ml and it has an accuracy of ± 1.0 ml at 20°C. Approximately 25 cm tall and 3 cm in diameter.

Which has greater accuracy the 10 mL graduated cylinder or the 50 mL graduated cylinder?

The 10ml would be more accurate.

How do you measure a graduated cylinder in mL?

The graduated cylinder will usually have heavy markings at 10, 20, 30, etc. milliliters. There are smaller markings in between the larger units called graduations. Read the graduated cylinder to the nearest tenth of a milliliter (46.5 mL or 20.0 mL).
