What tool is used to measure a liquids mass?
A pycnometer is such a tool. It is a carefully calibrated glass container with a close-fitting stopper. Since the volume is accurately known, a simple mass balance may be used to determine the mass of your unknown liquid. There are also techniques available for measuring the density of a non-soluble powder, using the same apparatus. In normal use, the pycnometer is filled with your unknown fluid, and weighed. Then the device is cleaned thoroughly of any residue, and a reference fluid such as water or mercury is used to fill the pycnometer. Simple arithmetic suffices to work out the density of the unknown material. Sometimes called the 'specific gravity bottle'.
Why is pycnometer only used to measure density?
pycnometer technique involves the intrusion of a non-wetting liquid at high pressure into a material through the use of a porosimeter. Porosimetry is an analytical technique used to determine various quantifiable aspects a materials porous nature, such as pore diameter, total proe volume, surface area, bulk density, true density etc. you can read more in the related link
What is the other name for polystyrene?
The other name for polystyrene is Styrofoam.
What is the other name of outer core?
The other name for the outer core is the metallic outer core.
What do you use to measure density?
Density is typically measured using a device called a hydrometer or by using the formula density = mass/volume. Other methods include using a pycnometer, which is a specialized flask used for measuring volume, or a balance to measure mass.
How do you properly use a pycnometer for measuring the density of a substance?
To properly use a pycnometer for measuring the density of a substance, first clean and dry the pycnometer. Then, weigh the empty pycnometer and record the mass. Fill the pycnometer with the substance, making sure there are no air bubbles. Weigh the filled pycnometer and record the mass. Calculate the density using the formula: density (mass of substance)/(volume of pycnometer).
What are the advantage and disadvantages of pycnometer?

How do you use piknometer?
A pycnometer is an instrument used to measure the density or specific gravity of liquids and solids. To use it, first fill the pycnometer with the liquid or solid sample, ensuring there are no air bubbles. Then, weigh the pycnometer with the sample and record the mass. Finally, calculate the density by dividing the mass of the sample by the volume of the pycnometer, which is typically calibrated and known.
Who invented the pycnometer?
1000-1048: Pycnometer: Abū Rayhān al-Bīrūnī
Why the pycnometer method more accurate than the hydrometer method?
The pycnometer method is more accurate than the hydrometer method because it uses an analytical balance.
When was the pycnometer invented?
According to the Wikipedia article on the gas pycnometer, the first patent was filed by John E. Shea on 13 Nov 1978 and it was issued on 08 Apr 1980.
What has the author A M Geddis written?
A. M. Geddis has written: 'Rapid estimate of solid volume in large tuff cores using a gas pycnometer' -- subject(s): Sampling, Soils, Volcanic ash, tuff, Pycnometer
What are the parts of pycnometer?
A pycnometer consists of a glass or metal container with a precise volume, a stopper or lid to seal the container, and a thermometer to measure the temperature of the liquid being tested. It may also have a hook or loop for suspending it in a fluid to measure its specific gravity.
Why the shape of pycnometer cap is conical?
Oh, dude, the shape of the pycnometer cap is conical because it allows for easy pouring and minimizes spillage when you're filling it up with liquid. Plus, the conical shape helps to create a tight seal, preventing any leaks or evaporation. So, like, it's basically designed to make your life easier when you're measuring the density of a substance.
How do you use a pycnometer?
Take G-DenPyc 2900 as an example: step 1. weight sample mass; step 2. put sample into sample chamber; step 3. cover sample chamber and switch gas on; step 4. input sample mass into analyzer software and click "start" to operation; step 5. about 5 mins to wait sample results.
Why is a conical cap provided to a pycnometer?
A conical cap is provided to a pscnometer to determine the volume of the test sample.
How is a substance's density calculated?
Density is the ratio beween the mass and the volume.Many devices exist in laboratory do determine the density: special analytical balance, pycnometer, helium pycnometer, densimeter (for liquids), electronic densimeter (for liquids) etc.; for perfect geometrical shapes the measurement of dimensions-calculation of volume-weighing are sufficient.
