10 litres of oxygen and 10 litres of at the same temperature and pressure have _________ masses.
According to Avogadro's law, under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules.
Example to illustrate Avogadro's law :
If 10 L of at S.T.P contains n molecules of then :
10 L of at S.T.P will also contain n molecules of
Molar mass of = (Mass of Mass of ) =
Molar mass of = ( Mass of )=
Mass of n molecules of
Mass of n molecules of
10 litres of oxygen and 10 litres of at the same temperature and pressure have unequal masses.
