The human Y chromosome is about 50 million base pairs long. One would expect to find 250,000 nucleosomes associated with this chromosome.
A nucleosome typically contains 200 base pairs. On dividing 50 million by 200, one would get 250,000 which would tell about the number of nucleosomes associated with the human Y chromosome.
