Why must the difference between the water level in the eudiometer tube and the water level in the beaker be measured?

The pressure of the gases in the eudiometer tube must equal the atmospheric pressure. If the water levels are not at he same height, then this is not the case. Therefore, in order to account for this difference and get accurate results, you must subtract the water levels and convert to mmHg.

What is the difference between a graduated beaker and beaker?
A graduated beaker has markings, either etched or painted, which indicate approximate volumes at several levels of the beaker.
What is the difference between glass and beaker?
well there really is know difference its just a beaker is a thiker kind of glass rather than ordinary glass!! ps if that helped please reply back:-)
What is the difference between a beaker and a flask?
The shape of the opening. A Beaker has a wide opening, the curved sides of the beaker do not converge. A flask has a narrow opening, the curved sides form a narrow neck, that can be bunged.
Mass by difference?
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
What measuring instrument is used in titration?
Titration involves the use of a buret and also an Erlenmeyer flask or beaker (where it is measured).
What is the difference between beaker and graduated cylinder in terms of measuring a volume of liquid?
beaker holds the H2o been measured by the graduated cylinder
How is density of a liquid measured?
The density of a liquid can be measured with a beaker. the beaker is weighed alone, then a specific measured volume of the liquid is placed in the beaker and the beaker is reweighed. The difference between the beaker with and without the water is noted. from there the mass of the liquid for the specific volume is then known. using hte formula d = m/v, we can therefore determine the density. where m is in kg and v is in liters.
50ml from a large beaker measured in a measuring cylinder is actually?
A small difference exist because the beaker is not calibrated for volume.

What is a beaker measured in?
in ml

Should we measure the mass of a beaker before measuring a chemical or powder inside the beaker?
You can do that or you can zero balance the scale with the empty beaker on it before adding the substance to be measured to the beaker.

Does density change if some of the liquid evaporates between the time the liquid is delivered to the beaker and to the time it was measured?
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
Is a beaker measured in ml?
Beakers can come in any measures.
Is measure a transitive verb?
It is transititve. For example, I measured the water in the beaker.
