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.
The idea is to divide the mass by the volume.
125 mL = 0.125 liters. The weight of the flask shouldn't matter.
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.
to make happy
make sure the flask is cooled about 15 minutes before weighing the flask to avoid the mass error
The volume of a liquid can be measured by any instrument with specific label of liters/millileter (most standard).Some items that can do this (in chemistry) are the beaker, the erlenmeyer flask, and for the most accuracy- the graduated cylinder.The mass of a liquid (labelled in grams) can be found by measuring the mass of the liquid's container, the mass of the container with the liquid inside of it, and then subtracting the difference using a triple beam balance:Mass of container and liquid combined - mass of container = mass of liquidThe density of a liquid can be found by dividing the liquid's mass by it's volume (labeled in grams per square milliliter).A beakerA measuring jug.

Density = mass/volume = 155/125 = 1.24 g/cm3.
