Question

State and explain avogadro's Law​

Answer 1

Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."[1]

For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperatureand pressure are constant.

The law is named after Amedeo Avogadrowho, in 1811,[2][3] hypothesized that two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same number of molecules. As an example, equal volumes of molecular hydrogen and nitrogen contain the same number of molecules when they are at the same temperature and pressure, and observe ideal gas behavior. In practice, real gases show small deviations from the ideal behavior and the law holds only approximately, but is still a useful approximation for scientists

Answer 2

Ciao,
According to this law " equal volumes of ll the ideal gassesat the same temprature and pressure contaim equal number of molecules
( this is for gsses)
and for elements it says thatbthe number of atoms,molecules and ions un one gram( one mole)
of an element is equal to 6.02× 10^23.
eg: 18g of H2o =:1 mole of water = 6.02×10^23molecules of water .
180g of glucose = same as above.
stay blessed
