What is the total volume of a 125 mL Erlenmeyer flask?
What is the total volume of a 125 mL Erlenmeyer flask?
A 125 mL Erlenmeyer flask has a measured volume of 152 mL.
What is the mass of a 125 mL Erlenmeyer flask?
– Mass of the 125-mLErlenmeyer flask + cover = 79.62 g – Mass of cooled flask and cover containing condensed liquid = 79.93 g – Temperature of boiling water = 99.5 ˚C – Volume of the 125-mL Erlenmeyer = 129.5 mL – Atmospheric pressure = 727 torr Using these data, calculate the liquid’s molar mass and identify the …
Why is it unnecessary to dry the Erlenmeyer flask in between measurements for the water and the unknown liquid?
If you are putting the ascorbic acid solution into a conical flask to do an experiment with it, then it definitely needs to be dry, since the water in the flask will change the volume slightly, and this will change the concentration.

How full should an Erlenmeyer flask be?
As a rule of thumb, a fill of 1/5 of nominal flask capacity should not be exceeded for microbial cultures, e.g. 100 mL for a 500 mL Erlenmeyer flask.
Why is it not necessary to dry the Erlenmeyer flask between each trial?
4. Repeat a second trial for the density of the water. Note: It is not necessary to dry the flask between trials because the 10.0-mL sample of water is weighed by difference.
How would it affect your results if you used a wet Erlenmeyer flask instead of a dry one when transferring your acid solution from the volumetric pipette?
How would it affect your results if you used a wet Erlenmeyer flask instead of a dry one when transferring your acid solution from the volumetric pipette? – With a wet Erlenmeyer flask, the result will not be accurate. It might be contaminated by any type of liquid such as basic or acidic.

How do you find the volume of a flask?
The density of a pure substance is equal to its mass divided by its volume: Density = mass volume or volume = mass density. The volume of the flask is equal to the volume of the water it contains. Since we know the mass and density of the water, we can find its volume and that of the flask.
Why do you need to rinse the sides of the Erlenmeyer flask with water?
Why does rinsing improve the accuracy of the endpoint? To make sure all the acid/alkali is at the bottom of the conical flask and can react, because as you swirl the acid/alkali can travel up the sides of the flask. Water isn’t an acid or an alkali so won’t change the number of moles needed in the flask.
Does the addition of water to the flask when you rinse down the sides during the titration affect the final result?
If liquid splatters on the inside of the flask, use a wash bottle to rinse the chemical from the sides. Adding water does not affect your results, since you are measuring the amount of acid in solution, not the amount of water present.
How would it affect your results if you used a wet Erlenmeyer flask instead of a dry one when transferring your vinegar solution from the buret?
