of one dozen each of different fruits are different in kg, i.e., 6.022 x102
a toms/ions/ molecules of different elements have different masses in gram and
this is equal to one mole of each element. This made Shashank to understand
mole concept.
(d) In one
mole of any substance, the number of particles (atoms/molecules/ions) is fixed,
with a value of 6.022 x 1023. This is called the Avogadro constant.
