The density of a substance in a sealed 2500 cm3 flask the is full to capacity with 0.36 of a substance?

Density 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)

What affect will water on the outside of the flask have in determining the density?
The density is lower.
Which description applies to a system in a sealed flask that is half full of water?
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.
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 size boiling flask would one use to distill 75m of ethanol?
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.
What is the pressure exerted by 1.55 g Xe gas at 20 C in a sealed 560 ml flask?
0,1013 MPa
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.
What affect will water on the outside of the flask have in determining the density?
The density is lower.
Why should you never heat a flask when sealed with a cork?
increased pressure and temperature
Substance that contains the vacuum in a vacuum flask?
Glass
Why you rinse titration flask with water?
To remove any substance that is already present in the titration flask from the previous titration
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.

How pressure capacity of glass flask is measured?
ASTM Standard C147-86
