My biology teacher has said that during mitosis, the number of chromosomes remains constant, so for humans that would be 46 chromosomes. But going through the steps of mitosis, that doesn't seem to make sense.
Prophase: We've been told that you have 46 chromosomes, each of which consist of two sister chromatids, for a total of 92 chromatids.
Metaphase: Again, 46 chromosomes and 92 chromatids.
Anaphase: This is where it doesn't seem to add up. During anaphase, the sister chromatids are pulled apart so we still have 92 chromatids, but these are all separated now. So surely the cell contains 92 chromosomes, from now until cytokinesis?
