It is a graduated cylinder.
See the Related Questions for more information about graduated cylinders.
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.
There's a graduated cylinder to measure liquid volume. It is a clear glass or plastic tube with mL markings on it.
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.
200 mL = a small glass of water 200 mL = 0.20 L
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.
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.
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.
Medically, for a usual 8 ounce glass of water, the equivalent in ML is 240ML.
It should say on the cylinder. Most of the ones I've seen are marked every 1 or 2 ml and labelled every 10 ml, or marked every 0.1 ml and labelled every ml.
Graduated cylinders are marked in milliliters (mL).
A small graduated test tube can measure 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.
