How many autosomes would be found in the normal liver cells of a human female?

Humans have 46 chromosomes in all body (somatic) cells. There are 22 pairs of autosomes and 1 pair of sex chromosomes. 

A karyotype is a chart with the chromosomes of an individual shown in homologous pairs for pairs 1-22. The final pair would be the person's sex chromosomes. Chromosomes are paired due to sexual reproduction. When a sperm containing a haploid set of chromosomes (23) and an egg with a haploid set (23) join at fertilization, the resulting zygote will have a diploid set of chromosomes (46).

A liver cell in a human female would contain 22 pairs of autosomes and a pair of sex chromosomes known as XX. It is the two X chromosomes that carry genes used for sex determination, while the autosomes are chromosomes that contain genes not related to sex-determination.

I have included a link showing a karyotype of a normal human showing the 22 pairs of autosomes, followed by an XX pair if the person was female, or an XY pair if the person was male.
