number of molecules
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
The ice cubes will help to keep the contents of the thermos flask colder for a longer period of time. The thermos flask's insulation will prevent heat transfer from the surroundings, helping to maintain the temperature of the ice cubes and the contents of the flask. Over time, the ice cubes will melt and help to cool the contents of the flask.
A flat bottom flask would be an Ehrlemeyer flask, which is used quite a lot by chemists.anf
The temperature in the flask remains constant because the peas act as insulation, limiting heat transfer between the inside and outside of the flask. This insulation effect prevents the temperature from changing easily.
volumetric flask
Once you have measured out your sample and transferred it to your flask, the absolute amount (moles) of sample is fixed. Adding water to the flask will change the concentration in the flask, titrating also adds volume to the flask as well as reacting with the sample. However, the number of molecules of sample you put into the flask will not change by simply diluting it with water.
Your intention is to transfer only the true sample into the conical flask, not the dirt from the scoop.
A measuring flask.
Volume of the flask = 131.5 mL - 125 mL = 6.5 mL = 0.0065 L
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).
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
Glass
Another word for a triangular flask is a conical flask.
Yes, a flask can have a meniscus. The meniscus refers to the curvature of the liquid surface in response to the container's shape. A flask with a narrow neck can exhibit a concave or convex meniscus, depending on the liquid it contains.
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.
UMMM....A bottle? i think it's called a decanter
Also known as a Buchner or vacuum flask, the flask uses vacuum to filter samples. A vacuum hose is attached to the hose barb and the funnel is placed on top. As the hose creates a vacuum, the sample is filtered through the funnel.
