The maximum amount of liquid a conical flask can hold is determined by its capacity, which is typically around 1 liter. However, you should avoid filling it to the brim to prevent spills and ensure accurate measurements.
There are 7.56 250ml units in 1.89 liters.
As a rule of thumb, your vol. should not be above 2/3 of total capacity of the flask. Do a back calculation for 75 mL EtOH, use ~150 ml capacity and above but try not to use too large boiling flask. I will stay say between 150-250mL.
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.
The empty flask contains the same number of air molecules regardless of whether it is at room temperature or immersed in a boiling water bath. However, when the flask is heated, the air molecules inside gain kinetic energy, leading to increased pressure. If the flask is sealed, some air might escape when heated, but the total number of air molecules present in the flask remains unchanged unless affected by external factors.
The answer depends on the graduation on the flask.
Not enough information has been given such as the height of the flask.
the height of a coffee mug would be about 8cm
Due to open space isolating the flask from external temperature
To dilute it to a certain concentration given in moles. It is best to transfer it to a beaker first to make sure it dissolves. The 250ml figure is dependent on how much of the solution that you need

250ml of milk = 250ml of milk 250ml of milk = roughly 256g of milk 250ml of milk = roughly 1 cup plus 2/3 of a tablespoon

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.

It varies from 226 to 250ml.
