Does the 100 ml graduated cylinder have the same uncertainty as 10 ml graduated cylinder?

It depends on the smallest unit. For a 10mL graduated cylinder, the smallest unit is usually 0.1mL while a 100mL graduated cylinder is usually 1mL. Therefore:
10mL= (0.1mL/2) is an uncertainty of 0.05mL
100mL=(1mL/2) is an uncertainty of 0.5 mL
Another way to think of it is that there are ten 10mL cylinders in an 100mL cylinder, so the 100mL cylinder has an uncertainty of ten times the 10mL.
Hope this helped!

∙ 16y agoIf the cylinders both have intermediary markings, go with the 10 mL. However, if you're that concerned about accuracy, you should use titration instead.

How do you measure uncertainty?
To measure uncertainty, you need to know the precision of the instrument, which refers to the smallest unit that an instrument can measure. A measurement can then be represented with its associated uncertainty, such as X = (5 +/- 1) cm. In this case, the actual value can deviate from the mean (5cm) by 1cm, so the minimum and maximum values ate 4cm and 6cm respectively. The percentage uncertainty is calculated by (absolute uncertainty / mean value) * 100%.
Who among the following is the more accurate in measurement the pipette or the volumetric pipette?
Theoretically a graduated cylinder...but if the only graduate I've got holds five liters with graduations 100 ml apart and I'm trying to measure to the milliliter, the pipette would be more accurate.
when was the micrometer screw gauge introduce?
A screw pitch gauge is a precision instrument. It is used for measuring diameter of circular objects mostly wires, with an accuracy of 0.001cm. It consists of a hollow cylinder mounted on a U frame. The hollow cylinder leads to a ratchet which is meant for fine adjustment. The U frame consists of a flat end known as stud and a screw on the other side. This screw can be moved inside the nut by fitted in the U frame by rotating the hollow cylinder called the thimble. This is called the main scale. The hollow cylinder or the thimble is graduated into 50 or 100 equal parts. This is called the circular scale
Which is heavier 100 pound brick or 100 pounds of paper?
their the same
Why is significant figures important is measurement?
Significant figures are important in measurement because they determine how accurate a scientific claim can be. There always has to be a small amount of uncertainty in an answer, because no measurement or calculation is ever 100% absolute.
When using a 100 mL graduated cylinder what decimal place do you use?
0.1
Up to what decimal place can you measure the volume of a liquid with your 100-ml graduated cylinder?
no. no you can't
What is the smallest measurable volume of liquid a graduated cylinder can hold?
its millilitres
Which graduated cylinder would be the best one to use to measure exactly 15ml of water Why?
Either a 100 mL or a 50 mL The 50 mL is better because you can see the meniscus against the graduated lines of the cylinder better.
What is The mass of a 100 ml graduated cylinder in grams?
That's depending of the design, outer measures, kind of glass, but merely on the thickness of (the wall and bottom of) the glass cylinder.
What tool is used to measure volume of an irregularly shaped object?
This would be called a graduated cillender. But the ccs vary in this tool...from 100 to 1000 * * * * * A graduated CYLINDER might be a better choice!
What do you use to measure milliliters?
a graduated cylinder. If you can find one that measures 100 mL, then this will be most accurate. If you find one that measures 1000 mL, this will be less accurate.
Which method do you prefer in determining for the volume of liquid?
It really depends on how much you are measuring. Like over 100ml and I'd stick to a large graduated cylinder. Under 1 ml (possibly up to 5ml even) and you could keep adjusting a micropipette until all the sample is just taken up for an estimate. 5-100, you could use a graduated cylinder for an estimate and calibrate the graduated cylinder against a burette
What is used for graduated cylinder?
A graduated cylinder is a piece of laboratory glassware used to accurately measure out volumes of chemicals for use in reactions. They are generally more accurate and precise for this purpose than beakers or erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipet. They come in a variety of sizes for different volumes, typically 10 ml, 25 ml, 50 ml, or 100 ml and up to as large as 1 or 2 liters. Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level.

What is the percent uncertainty for the measurement given as 4.19m?
When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100. 4.19m take the last decimal unit, is 9 but with value of 1/100 .01 is the uncertainty Now, .01/4.19 x 100 % = 0.24%
How many significant figures can be recorded in the measure of the fluid and the graduated cylinder?
A 100 mL graduated cylinder is graded in divisions of 1 mL giving results which have 2 significant figures. Cylinders for measuring up to 10 mL to have divisions at 0.1 mL, so again giving 2 sig figs.2 digits. .
