because of the density of iron is more that is why iron is
heavier & mass accumulated in the iron is also more .

Both are same.The mass of each is 1 kg.But 1 important
point the weight of two may not be the same(mg).This is
because as the cotton is porous and can have some air
inside its pores as well as its volume will be
considerable.It will experience an upward buoyant
force.Hence the effective weight=the weight mg(act down)-
the upthrust(act up),which is volume of cotton(net with
pores)*density air*g.

Answer
# 16
generally weight is product of mass*g
but mass=volume *density.iron is more densed,and cotton
occupies more volume .so both will get cancelled.so both
will have the same weight.

Answer
# 18
1kg of iron.because of 1st density of iron 2nd because of
the air that each of them occupied sth like ARASHMIDOS
low...

Answer

The question is which one is heavier.The question is not which one will fall soon.So no buoyancy effect comes into picture.

what rest is the weight.Now w=mg.
1 kg mass is a constant and standard value in anywhere in the universe.
So both iron and cotton are having same amount of matter
(1 kg) in it.

Remember the air inside the cotton will not be taken into account as we are taking pure 1kg of cotton.If you are taking air then it will be more than 1 kg of cotton.

So they will experience (1*9.81) N both in earth ground.
So the answer of the question is they are same as weight though volume of 1 kg cotton is larger than 1kg of iron.


***********
(If they are freely falling then the cotton will take much time due to large volume and so bigger buoyancy effect of air.
In space they will take same time to fall a distance.)
