If A flask contains 440 mol of liquid bromine Determine the number of bromine molecules in the flask?
There are approximately 2.65 × 10^26 bromine molecules in the flask. This is calculated by multiplying Avogadro's number (6.022 × 10^23 molecules/mol) by the number of moles of bromine present in the flask (440 mol).
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.
What is the use of iodine flask?
An Iodine Flask is essential an Erlenmeyer Flask with a stopper used for the wet chemical analysis "Iodine Determination" . This analysis is typically performed on fatty acids, oils and shellac varnishes.
What is Erlenmeyer flask and its uses?
Erlenmeyer flask is a conical flask made from glass or plastic, sometimes graduated or with a stopcock; uses: - to contain liquids or powders - to realize chemical reactions - it is the preferred flask for titration - heating of liquids (only in Pyrex glass) See also the link below.
A flask contains 0.500 of liquid bromine Determine the number of bromine molecules present in the flask?
To find the number of bromine molecules in the flask, first determine the molar mass of bromine, which is 79.904 g/mol. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert the mass of bromine in the flask to the number of molecules. This will give you approximately 1.66 x 10^22 bromine molecules in the flask.
What does the Erlenmeyer flask measure?
A graduated Erlenmeyer flask can measure a volume.
What are ways to measure volume?
Beaker, flask, jug.
Is a Conical Flask used to measure?
not unless it is graduated
How do you measure 6.9 quarts?
Use a calibrated flask.
Can an Erlenmeyer flask measure in grams?
No. An erlenmyer flask measures volume, usually in mililiters, but sometimes in liters. Grams is a measurement of mass, and to measure mass you need a ballance.
What unit would you use to measure a small flask?
Milliliters.
What is a flask used to measure?
Its used for concentration, when you want to dillute something.
What are the function of volumetric flask?
to measure liquids and other chemical fluids
What it use to measure the volume of solution?
A measuring flask or graduated cylinder.
What is the accurate apparatus to measure volume of water?
Depending upon the amount of substance you are using and what it is, you could use a graduated cylinder, Erlenmeyer flask, or a beaker.
What piece of equipment is necessary to measure a precise amount of fluid?
A small amount or a large amount? For small amounts pipettes are useful. Micropipettes are usually pretty precise. Burettes and graduated cylinders are also precise when used properly. It depends on what you are measuring and how much and what for.
Could a 25 ml volumetric flask be replaced by a 25 ml pipette to measure the solution poured into a conical flask for titration?
As the pipette is far more accurate than a flask by a factor 10 to 100 one should NOT use a volumetric flask except for standard volumes over 100 ml.
