Question

please state Avogadro's law and give two simple example s

Answer 1

AVOGADRO's LAW :-

this is very important law in chemistry as well as physics ( thermal physics ) .
according to this law , under similar condition of temperature and pressure ,equal number of all gases contain equal number of molecule .

in easy way we can say that ;
in gases equation ,
PV = nRT

if P = constant
T = constant

then, V is directly proportional to n
e.g volume of gases is directly proportional to no of mole and no of mole is directly proportional to no of molecule { no of molecule =no of mole ×6.023 ×10²³) so,

volume of all gases contains equally when , no of molecule are equal at same temperature and pressure.

★ Avogadro's law is the soul of mole concept.

// Avogadro's law is an experimental defined law so, tough to give example by which you understand .
so, I use chemical equation , becoz generally chemical reaction at constant temperature and pressure .
example :-
2H2 + O2 →2 H2O

mole of H2 = 2
mole of O2 = 1
mole of H2O =2

no of mole of H2 = no of mole of H2O

becoz temperature and pressure are constant , so,
volume of H2 = 2 × 22.4 L = 44.8 L
volume of O2 = 22.4 L
volume of H2O = 2 × 22.4 L =44.8 L

volume of H2 = volume of H2O
hence, at constant temperature and pressure , no of mole are equal then ,
volume will be equal .
this is what ????
off course Avogadro's law .

Answer 2

devgad road number number particle present in 1 mole of any substance is affixed with value of 6.0 to 2 x 10^ 23 this is experimentally obtain the value this number is called the avogadro consists of avogadro number name in honour the Italian scientist amedgo avogadro
for example the atomic mass of hydrogen =14
sau gram atomic mass of hydrogen = 1 g
1 u hydrogen has only one atom of hydrogen
1 g hydrogen has one mole atom that is a 6.022 × 10^23 atom of hydrogen
