Humans usually have 46 chromosomes. Monkeys, chimps, or other organisms related closely to them: they have diploid number of 48 chromosomes. 
(Future reference: Haploid means half, half the # of chromosomes in the nucleus. Diploids means duplicate, COMPLETE necessary set of chromosomes).
Hope it helps!! :)
