How many chromosomes are in each cell at the beginning and at the end of the mitosis process

A cell will typically have 46 chromosomes. During S phase in Interphase. All 46 chromosomes are replicated and double. Now we have 92 chromosomes. When the cell goes into Mitosis stage, the # of chromosomes are halved. So 92/2= 46 chromosomes. The cell divides into 2 cells each with 46 chromosomes. I hope this helps. I may be wrong so here's a link to a video explaining Mitosis.
