Can you use a erlenmeyer flask to calculate the density of a liquid?
You can, but the volume will not be as accurate as using a graduated cylinder, and will probably give you an inaccurate density.
How did Louis Pasteur experiment differ from lazzaro spallanzani experiment?
Instead of sealing the flask in the experimental group after boiling, Pasteur used a flask with a curved neck, which allowed air inside and outside the flask to mix but prevented microorganisms from entering the body of the flask.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
Yes
Why was it necessary to match the water levels inside and outside the cooled flask before removing it from the water bath?
So to equalize the pressure inside the flask with that of the atmosphere.
How do you calculate density of cyclohexen?
cyclohexane is a liquid so it may be filled in a flask of known volume and may be weighted out ... the ratio of mass and volume represents the density....
How does a thermos flask reduce conduction?
There is air between the inside and outside of the flask.
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?
The gas pressure in the flask is lower than the atmospheric pressure when the water level is higher inside than outside the flask.
How would I calculate the mass of air in an empty flask?
From the volume of the flask, and the density of air under the conditions in the room, you can calculate the mass of air. The density of air varies with pressure, temperature, humidity, etc. At sea level and at 15 °C air has a density of approximately 0.001225 g/ml, so under these conditions, a liter flask would contain (1000 ml)(0.001225 g/ml) = 1.225 g of air.
Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.
How do you make a balloon reverse it's position without anyone touching it so that it inflates outside the flask rather than inside the flask?
Once again, heat the flask with the balloon on the inside. The cooled molecules will speed up again, creating energy. If the flask is left on the heat, the air pressure will grow, causing the balloon to be pushed back to the outside of the flask.
A flask that weighs 345.8 g is filled with 225 ml of carbon tetrachloride The weight of the flask and carbon tetrachloride is found to be 703.55 g Calculate the density in gml and gL?
If the weight of the flask and compound are 703.55 and the flask weighs 345.8, then the compound weighs 357.75 grams. Then the density in grams per milliliter is 1.59 g/mL (357.75 g / 225 mL). There are 1000 milliliters in one liter, so the density is also .00159 g/L.
What equipment except Archumedes principle that can measure density of material?
An old instrument that works very well for solids and liquids is a pichnometer. It is a glass flask with a defined, exact volume and you determine the density by weighing the pichnometer full of water (known density at a specified temperature), the empty flask and the flask with a small amount of the solid or full of a liquid. Note: The liquid or solid should not dissolve in water. If the do, use a standard liquid of known density that will not dissolve the sample

An alternative procedure for determining the density of a liquid would be to pipet a sample of the liquid into a weighed flask then reweigh the flask to determine the mass of liquid transferred?
Yes, pipetting the liquid into a weighed flask and then weighing it again would give you an indication of the density of the liquid. The answer would, however, not be as accurate as when you use specialized equipment for the measurement. Depending on your application this difference might or might not be significant. If you are in doubt and a hurry it could be best to do your measurement the way you described it and state your method clearly in your report. Just remember to use as big a volume as possible (eg. a 100ml pipette), to minimse the effect of possible pipetting inaccuracies (eg. parralax error, ect.).
