What affect will water on the outside of the flask have in determining the density?
Water on the outside of the flask will not affect the density measurement of the contents inside the flask because density is a property intrinsic to the material being measured and is not influenced by external factors like water on the surface. To determine the density of the contents, only the mass and volume of the material inside the flask need to be considered.
Why is it important that the flask be sealed for this experiment even after the flask is returned to an upright position?
Keeping the flask sealed after it is returned to an upright position prevents any air or gas from escaping, ensuring that the pressure inside the flask remains constant. This helps to maintain the accuracy of the experiment's results by keeping the conditions consistent.
Which description applies to a system in a sealed flask that is half full of water?
There are a number of things you can say about a sealed, partially filled flask. If you notice condensation on the inside of the container, then you can say that dynamic equilibrium has been reached. This is where the rate of evaporation is equal to the rate of condensation.
Are all Erlenmeyer flask the same in weight?
No, Erlenmeyer flasks can vary in weight depending on the material they are made from. Glass Erlenmeyer flasks are typically heavier than plastic Erlenmeyer flasks due to the density of glass. Additionally, the size and volume capacity of the flask can also affect its weight.
Is the volume occupied by the gas in the flask approxmately the same greater or less than before it was heated?
Assuming the flask is sealed - the volume remains the same but the pressure increases
What is the density of a substance in a sealed 25000 CM flask that is full to capacity with 3600 G of a substance?
The density of the substance in the flask is 1.44 g/cm^3 (3600 g divided by 25000 cm^3).
What is the volume capacity of a flask?
The answer depends on the flask: they are not all the same size.

If you cool a flask to -200degrise what would happen to the air?
I the flask was sealed, the air inside of the flask would take up less space and as a result, cause a drop in pressure inside the flask.
Substance that contains the vacuum in a vacuum flask?
Glass
Why should you never heat a flask when sealed with a cork?
Heating a sealed flask with a cork can cause pressure to build up inside and potentially lead to an explosion. As the contents of the flask heat up, they expand and create more pressure inside the sealed container, which the cork may not be able to withstand. It's safer to use a vented closure or open container when heating substances.
Why should the distilling flask be filled to no less than one thirds of its capacity?
If the neck of your flask is short, you don't want to fill the flask too high (more than about 1/2), or else liquid from the flask will enter your distilling tube and get distilled out when you heat it. Remember the idea of a distillation is to heat up your substance to the vapor phase and let the vapor diffuse toward the distillation tube so that only purified product drips into the collecting 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.
