Haploid is represented as "n" - only one copy. Diploid is represented as 2*n. Triploid is represented as 3*n, and so on.

If you have 5, then n = 5.

In a normal cell, it would be 10 because 2*n Rightwards Arrow 2*5 = 10. All somatic cells (cells that undergo mitosis) are diploid.

During mitosis, the diploid number, in this case 10, doubles so it becomes 20. It doubles, as we know, because each new cell needs 10 chromosomes.
