β 14y agoDensity is mass per unit volume. So this gas has a density of:
0.36 / 2500 = 0.000144 mass units per cm3
or 0.0144 mass units per liter
or 14.4 mass units per cubic meter
(as you have not define the units of mass I cannot be more specific)

β 14y agoTo find the density, first calculate the volume of the substance in the flask: 2500 cm^3 * 0.36 = 900 cm^3. The density can be calculated by dividing the mass of the substance by its volume. Additional information, such as the mass of the substance, would be needed to find 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.
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.
The system in the sealed flask that is half full of water can be described as a closed system since nothing can enter or leave the flask. Additionally, it can be regarded as an equilibrium system since the water level remains constant and there is no net change in the system.
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.
Assuming the flask is sealed - the volume remains the same but the pressure increases
The density of the substance in the flask is 1.44 g/cm^3 (3600 g divided by 25000 cm^3).
The answer depends on the flask: they are not all the same size.

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.
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.

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.

To calculate the mass of the air in an empty flask, you would first weigh the empty flask. Then, you would fill the flask with air and weigh it again. The difference in weight between the two measurements would give you the mass of the air in the flask.
For distilling 75 mL of ethanol, a boiling flask with a capacity of at least 100 mL would be suitable. The flask should have some extra capacity to prevent overflowing and accommodate any necessary headspace during distillation.
