I was never taught why it needs to be this value. My handwaved answer is "to make balancing equations easier." The real answer seems to require me to look up wtf a dalton is and why that was chosen.
The number 6.02214076×1023 (the Avogadro number) was chosen so that the mass of one mole of a chemical compound in grams is numerically equal, for most practical purposes, to the average mass of one molecule of the compound in daltons. Thus, for example, one mole of water contains 6.02214076×1023 molecules, whose total mass is about 18.015 grams and the mean mass of one molecule of water is about 18.015 daltons
