The only way to know is to weigh it. The mass of two apparently identical flasks is quite variable.
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.
Oh, dude, the mass of a 50 ml Erlenmeyer flask is gonna depend on the material it's made of. If it's glass, it might weigh around 50-100 grams, but if it's plastic, it could be lighter. Just slap that bad boy on a scale to find out for sure. Like, it's not rocket science, man.
The idea is to divide the mass by the volume.
density = mass / volume = 1.24 g/ml
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.
If the balloon was removed from the flask, the mass of the flask and its contents would remain the same because the air inside the balloon is still part of the system. Removing the balloon does not change the total mass of the system.
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.
Density = mass/volume = 155/125 = 1.24 g/cm3.

If the balloon is not placed on top of the flask, the mass inside the flask would remain the same, but gas and vapors may escape into the air, potentially leading to a decrease in the overall mass if measured after some time. Additionally, any reactions occurring inside the flask might release gases or substances that could alter the mass. Without the balloon, it would be challenging to contain and observe changes in pressure or gas accumulation.
If the balloon is not placed on top of the flask, the mass inside the flask would remain constant. The balloon is used to capture any gases produced during a chemical reaction, which would otherwise escape into the environment. Without the balloon, the mass of the gases released would not be accounted for, leading to inaccurate measurements of the total mass change in the system.
