Explanation:
i've taken the test
A volumetric flask is used to contain a predetermined volume of substance and only measures that volume, for example 250 ml.
Conical flasks can be used to measure the volume of substances but the accuracy they provide is usually up to 10ml. Conical flasks are used in titrations, reactions where the liquid may boil, and reactions which involve stirring.
Pippettes are of two types, volumetric and graduated. Pippettes are used where high accuracy is required and volumetric pippettes come in as little as 1 ml. Pippettes are usually used in titrations.
Graduated cylinders come in a wide variety of sizes and their accuracy can be down to as much as 1 ml. They are used to contain liquids.
Carbon's molar mass is 12gm
Oxygen's molar mass is 16gm
So CO2 molar mass is 44gm
Hence 1mol of CO2 contains 44gm
There 1/4mol of CO2 contains 44/4=11gm.
Hope it helps
