How do you tell if the daughter cells are diploid or haploid? explain:

Diploid cells contain two complete sets (2n) of chromosomes.

Diploid cells reproduce by mitosis making daughter cells that are exact replicas.
 
here is your answer

The difference between haploid and diploid cells is related to the number of chromosomes that the cell contains.
Haploid:1 copy each chromosome, one sex chromosome, reproductive cells
Diploid:2 copies each chromosome, 2 sex chromosome, not reproductive cells
Mitosis produces 2 genetically identical daughter cells. Meiosis produces 4 genetically different daughter cells. 
Diploid cells contain two complete sets of chromosomes. Diploid cells reproduce by mitosis making daughter cells that are exact replicas. So, to determine if a daughter cells is diploid or haploid, figure out what process they underwent (mitosis or meiosis) by comparing them to their other "half". If they are identical, you know they're diploid. 

I hope this helps:)
