Why was it important to determine the mass of the air in the flask?
Determining the mass of the air in the flask allows for the calculation of the density of air, which is important in various scientific and engineering applications. It also provides insight into the composition and properties of the gas inside 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?
When the water level is higher inside than outside the flask, the gas pressure in the flask is lower than the atmospheric pressure. This is because the weight of the column of water inside the flask creates an additional pressure on the gas inside, reducing its pressure relative to the atmospheric pressure outside.
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.
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.
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.

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.
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.

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.
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).
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.
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.

You can, but the volume will not be as accurate as using a graduated cylinder, and will probably give you an inaccurate density.

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....
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
