How do you find the volume of a flask?

Find the mass of the empty flask. Fill the flask with a liquid of known density (e.g., water at 23°C), and measure the mass of the liquid-filled flask. Subtract to find the mass of the liquid. Using the known density and mass, calculate the volume.

How much does a 250ml glass beaker weigh?

An empty 250ml beaker has a mass of 60 grams. When 100ml of oil is added to the beaker, then the total mass is 140g.

How heavy is a flask?

76 pounds
Flask is a British unit of mass or weight in the avoirdupois system, used to measure mercury. It is defined as 76 pounds (34 kg).

What is graduated cylinder used for?

Graduated cylinders are long, slender vessels used for measuring the volumes of liquids. They are not intended for mixing, stirring, heating, or weighing. Graduated cylinders commonly range in size from 5 mL to 500 mL. Some can even hold volumes of more than a liter.

Is an Erlenmeyer flask precise?

Erlenmeyer flasks are not accurate enough for precise measurements of solutions, so scientists must rely on graduated cylinders and other tools when precision is necessary. Flasks are usually made of glass, which is heat resistant and can be autoclaved (heat-sterilized) or heated by open flame.

What is a conical flask?

An Erlenmeyer flask, also known as a conical flask ( BrE) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825-1909), who created it in 1860. Oct 10 2019

What is a flask in chemistry?

Flasks are useful types of chemistry glassware for containing liquid and performing mixing, heating, cooling, precipitation, condensation, and other processes. These flasks –also known as a science flask, chemistry flask, or a laboratory flask (lab flask) – come in a range of sizes, materials, and uses.
