Question

ual volumes of all gases at the same

temperature and pressure contain equal
number of molecules ", is the statement of

which one of the following law?*


​

Answer 1

Answer

This is called as the Avogadro's Law

• The Avagadro's Law was stated by Amedeio Avagadro. It states that, at equal volumes of all gases at the same temperature and pressure will contain equal number of molecules

• He said that one mole will contain 6.0222×10²³ molecules

• This number is called as Avagadro's number

• Avogadro's number was discovered in 1909

• Avogadro derived his law with the help of Lussaic's law

1 mole = Given Mass/Molar Mass

• Lussaic's law states that the pressure at a given mass will change as per the temperature of the gas
