Understand that mitosis is a process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the original cell.
Recall that human somatic cells are diploid, meaning they have two sets of chromosomes, totaling 46 chromosomes (23 pairs).
During mitosis, the chromosomes are duplicated during the S phase of the cell cycle, resulting in 92 chromatids, but these are not counted as separate chromosomes.
In telophase, the chromatids are separated into two new nuclei, and each daughter cell receives a complete set of chromosomes.
Therefore, each daughter cell will have 46 single chromosomes, which is the same number as the original cell before division.
