What is the uncertainty of a 50 ml glass gas measuring tube?
It depends on the tube's construction. Assuming a graduation every one millimetre, a 50 mm high tube can measure to +/- 0.5 ml accuracy. A 200 mm high (very thin!) tube, also with one mm graduations, is four times as accurate. You need to state the smallest actual graduation to get your answer, and be aware that the liquid's meniscus affects reading confidence.
How do i get 160ml of water in a glass?
To get 160 ml of water in a glass, you can use a measuring cup or a kitchen scale for accuracy. Pour water into the glass until it reaches the 160 ml mark on the measuring cup, or weigh out 160 grams of water if using a scale, since 1 ml of water is approximately equal to 1 gram. Once you have the correct amount, you can adjust as needed to ensure it's precisely 160 ml.
What containers used to measure?
There's a graduated cylinder to measure liquid volume. It is a clear glass or plastic tube with mL markings on it.
If there is 50ml left in a glass and the glass holds 150cc how much was removed?
An ml is equal to a cc so if the glass originally held 150cc (ml) and there is 50cc (ml) left then 100cc (ml) had to have been removed.
How many liters are in a glass of water?
200 mL = a small glass of water 200 mL = 0.20 L
How many glass of water in 140 ml?
There are approximately 0.59 standard-sized glasses of water in 140 ml. A standard glass of water is typically around 240 ml, so dividing 140 ml by 240 ml gives you 0.5833. This means you would have a little over half a glass of water in 140 ml.
What is the accuracy and precision of graduated cylinder and what is the use of graduated cylinder?
The accuracy of a graduated cylinder depends on its calibration and the smallest increment on its scale. The precision is determined by the volume intervals marked on the cylinder. Graduated cylinders are used to measure and hold liquid volumes with good accuracy and precision in experiments and laboratory settings.
What ML quantity is a glass of water medically?
Medically, for a usual 8 ounce glass of water, the equivalent in ML is 240ML.
What 50-mL graduated cylinder is marked into 1-mL segments?
A 50-mL graduated cylinder marked into 1-mL segments would have markings at every 1 mL increment from 0 to 50 mL. This means it would have a total of 50 markings on the cylinder at every 1-mL interval.
What instrument is used to weigh a glass of water in ml?
Millilitres, ml, is a unit of volume rather than weight. The weight (strictly the mass) of a glass of water would be measured in grams. To weigh a glass of water, you'd just put it on a simple top pan balance. To measure the volume, you'd transfer the water to a vessel with a calibrated scale on the side, eg a measuring cylinder.
What is the test tube's total volume?
To determine a test tube's total volume, you typically need to consult the manufacturer's specifications or markings on the test tube itself. Test tubes come in various sizes, commonly ranging from 5 mL to 50 mL or more. If the test tube is marked with volume graduations, you can also use those to assess its total capacity. Otherwise, measuring the volume by filling it with water and pouring it into a graduated cylinder can provide an accurate measurement.
How is liquid volume measured?
Liquid Volume Measuring Devices: The Graduated Cylinder and Buret Like weighing, measuring liquid volume is a fundamental and frequently encountered lab task. However, liquid volume is frequently measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass (or plastic) tube sealed at one end with a calibrated scale etched (or marked) on the outside wall. Graduated cylinders come in a range of sizes (volume capacities), and much like a measuring cup, volume is measured by adding liquid to the cylinder and comparing the liquid level to the graduated scale. The measured volume corresponds to the volume of liquid contained in the cylinder. Hence, the graduated cylinder and devices like it (volumetric flasks, Erlenmeyer flasks, and beakers) are classified as to-contain (TC) devices. The volume of liquid in the graduated cylinder is obtained directly by reading the calibrated scale. In most situations, the liquid will be water or an aqueous solution.The liquid surface is curved (U-shaped) rather than horizontal due to the relatively strong attractive force between water and glass. (The curved surface is called the meniscus.) As a general rule, the bottom of the meniscus is taken as the liquid level in the cylinder (and any other volume measuring device). The scale divisions on a graduated cylinder are generally determined by its size. For example, the 50-mL graduated cylinder is divided into 1 mL increments. However, the scale of a 10-mL graduated cylinder is divided into 0.1 mL increments, and the scale of a 500-mL graduated cylinder is divided into 5 mL increments.The graduated cylinder scale is a ruled scale, and it is read like a ruler. The scale is read to one digit beyond the smallest scale division by estimating (interpolating) between these divisions. With a 50-mL graduated cylinder, read (and record) the volume to the nearest 0.1 mL. The 10-mL graduated cylinder scale is read to the nearest 0.01 mL and the 500-mL graduated cylinder scale is read to the nearest milliliter (1 mL).A buret is a scaled cylindrical tube attached to a stopcock (valve). A buret is designed to dispense or transfer a precisely measured volume of liquid to another container. The volume of liquid dispensed is determined by reading and recording the buret scale which corresponds to the liquid level in the buret before any liquid is transferred, Vinitial (or Vi),and after the transfer is complete, Vfinal (or Vf). The volume of liquid transferred is obtained by difference (Vf - Vi) and it is sometimes designated as Vt.Burets are available in a limited range of sizes; the most common size is 50-mL. The scale of a 50-mL buret is divided into 0.1 mL increments. Therefore, when the liquid level in a buret is read, it is read (and recorded) to the nearest 0.01 mL. Water or aqueous solutions are the most common liquids used with a buret, and like the graduated cylinder the bottom of the meniscus is taken as the liquid lever. The buret and devices like it (pipet and syringe) is classified as a to-deliver (TD) devices.
