How do you read a 100 mL graduated cylinder?
The 10-mL graduated cylinders are always read to 2 decimal places (e.g. 5.50 mL) and the 100-mL graduated cylinders are always read to 1 decimal place (e.g. 50.5 mL). so that the line at the bottom of the meniscus gives the most accurate reading.
What are the lines on a graduated cylinder?
A graduated cylinder, also known as a measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.

How do you read upper and lower meniscus?
If the meniscus is a concave meniscus, read at the lowest level of the curve. If the meniscus is convex, take your measurement at the highest point of the curve. The short answer: Take your measurement from the center of the meniscus. It's that easy.
How do you read a 50 mL graduated cylinder?

How do you read a 25 mL graduated cylinder?
In the 25-mL graduated cylinder, first subtract 25 mL – 20 mL = 5 mL. Next, count that ten intervals are between the labeled graduations. Therefore, the scale increment is 5 mL/10 graduations = 0.5 mL/graduation.
How do you read the volume of a test tube?
Measure the volume of the sample from where it starts at the bottom of the tube to the base of the meniscus (for liquids) or the top layer of the sample. Don't measure the test tube from the bottom of the base to where it ends.
How do you read a 10mL graduated cylinder?
If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL). Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder.
When measuring a liquid How do you read the measurement?
Measure so that the line you are reading is even with the center of the meniscus. For water and most liquids, this is the bottom of the meniscus. For mercury, take the measurement from the top of the meniscus.
How do you measure volume of water?
Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C). Find the capacity in gallons of a horizontal circular tank that has a diameter of 8 ft and is 12 ft long.
Do you read the bottom of the meniscus?
The key to getting an accurate reading, is to measure the center of the meniscus whether it be concave or convex. E.g. with a concave meniscus, measure the bottom of the meniscus and for convex meniscus, take the reading from the top of the meniscus.
Why do you read from the bottom of the meniscus?
The location of the mark on the glass is where the bottom of the meniscus should be in order to have the "true" volume be what's marked. So by measuring from the bottom of the meniscus, you're synchronizing your measurement procedure with the procedure of the people who originally calibrated the markings on the glass.

How do you measure volume of a liquid?
Pour the liquid into the container and record the weight of the container plus the liquid. Subtract the weight of the container to get the weight of the liquid. Look up or calculate the density of the liquid, then determine the volume of the liquid by dividing the mass of the liquid by the density.
Is a 10 mL or 50 mL graduated cylinder more precise?
Most 50 ml graduated cylinders have markings spaced every milliliter while 10 ml graduates have markings every tenth of a milliliter. If we measure a small volume of liquid in a 10 ml graduate, our measurement should be more accurate than if a 50 ml graduate were used.
What volume is 1 mL of water?
1 cubic centimeter One milliliter (1 mL) of water has a volume of 1 cubic centimeter (1cm3).
How do you figure gallons in a cylinder?

What part of the meniscus do you read?
The key to getting an accurate reading, is to measure the center of the meniscus whether it be concave or convex. E.g. with a concave meniscus, measure the bottom of the meniscus and for convex meniscus, take the reading from the top of the meniscus.
Do You measure water from the top or bottom of the?
For water and most liquids, this is the bottom of the meniscus. For mercury, take the measurement from the top of the meniscus. In either case, you are measuring based on the center of the meniscus.
Why do we need to read the lower meniscus and not the upper meniscus?
Answer. Answer: The lower meniscus must be read while measuring the volume of colourless or transparent liquids but the upper meniscus while using colured ones because the phase boundary in the colourless liquid is clearly visible so it is easy to read it.
How do you count ml?
Divide the mass in milligrams by volume in milliliters to find concentration in mg/mL. For example, if you have 8,000 milligrams of sugar dissolved in 200 milliliters of water, work out 8,000 ÷ 200 = 40. The concentration of the solution is 40 mg/mL.

- 0.5 ml = ⅛ teaspoon.
- 1 ml = ¼ teaspoon.
- 2 ml = ½ teaspoon.
- 5 ml = 1 teaspoon.
- 15 ml = 1 tablespoon.
- 25 ml = 2 tablespoons.
- 50 ml = 2 fluid ounces = ¼ cup.
- 75 ml = 3 fluid ounces = ⅓ cup.
How do you calculate volume of water?
Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C). Find the capacity in gallons of a horizontal circular tank that has a diameter of 8 ft and is 12 ft long.
How do you calculate volume of a liquid?
The volume of a container is the amount of space it encloses; or how much space is inside of it. For a box, the volume is determined simply by this formula: A box with height H, width W and length L, has volume V = L × W × H.
Do you read from the top or bottom of the meniscus?

How do you write volume in ml?
Milliliters are often written as ml (for short), so "100 ml" means "100 milliliters". Here we have 150 ml of milk in a measuring cup. It doesn't say "150" … it says "50" … but it is half-way between 100 and 200 so you can figure out it is 150 ml.
