we hear cotton is lighter than iron right?

Ok Suppose that,

The weight of cotton = 1kg

& the weight of iron = 1kg

Since, the density of cotton is lesser than the density of iron , the total volume of 1 kg cotton will be higher than the 1 kg of iron as a result an upward force called buoyant force will be exerted on the cotton by the air this buoyant force will be larger on cotton than on the iron as it is equivalent to the weight of the air being displaced.

In this way, cotton is lighter than the iron.
