How many units in a 1 Millimeter Pipette?
25 ml
You are using a pipette that has a mark every 0.1 mL. If you want to measure 5.15 mL of liquid using this pipette to what level should you fill the pipette?
The bottom of the meniscus should be halfway between the 5.1-mL mark and the 5.2-mL mark
How would you prepare 20 ml of a 1 to 400 dilution?
If accuracy is not a problem the most simple way to produce 20 ml of a 1:400 dilution is to take 1:400 of 20 ml (i.e. 0.05 ml) of the original solution and add 19.95 ml of liquid. As pipettes are the most precise close to their maximum uptake volume and micro-pipettes are inherently much less precise than pipettes for larger volumes I'd do a two-step dilution. 1. step: 1.000 ml of original solution with 1 ml pipette + 4 times 4.750 ml with 5 ml pipette 2. step: 1.000 ml of solution from step 1 + 4 times 4.750 ml with 5 ml pipette.
What is the accuracy of a 10 millilitre bulb pipette?
A bulb pipette class A has an accuracy of 0,02 mL.
How could you determine how many drops from the pipette of the dropper equal 1 ml?
20 drops = 1ml 20 drops = 1cc 1ml = 1cc
What is used of volumetric pipette?
The purpose of a volumetric pipette is to deliver a precise amount of a liquid. The label on the pipette indicates the volume delivered (e.g. 10.00 mL).
How do you measure how much water a tablespoon holds?
the answer is 1 tablespoon = approx. 15ml
Are milliliters equal to grams?
yes and no because water has a volumic mass of 0,89g/mL Approximative so 1g/mL is not right.
What is measure pipette?
A pipette is a tube like tool used in chemistry to intake liquids. A measure pipette is the same thing, it just has measurements labeled on the side so you can know how much you are using.
What can measure ml of liquid material in chemistry?
We can use a graduated pipette, a small cyllinder, a burette.
Could a 25 ml volumetric flask be replaced by a 25 ml pipette to measure the solution poured into a conical flask for titration?
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
What measures exactly ml of sodium chloride?
A volume can be measured in laboratory with a graduated cylinder or a graduated pipette.
