1.	Write short notes on Avogadro’s Hypothesis and its applications.
Answer» Avogadro’s-Hypothesis and its applications: In 1811, Italian physicist and mathematician Anedeo Avogadro published a hypothesis (also termed Avogadro’s law or principle) states that the volume of a gas is directly proportional to the number of molecules of the gas. This is represented by the formula , V = aN, where a is a constant, V is the volume of the gas, and N is the number of gas molecules. Applications Avogadro’s law has been useful in substantiating a number of important laws and concepts. It has helped in the following areas: (i) In explaining Gay Lussac’s law of gaseous volumes. (ii) In determining the atomicity of gases. (iii) In determining the molecular formula of a gas. (iv) In establishing the relationship between relative molecular mass and vapour density.
