[ Chemistry ] Open Question : How much of a 1M NaCl solution should you add to 28L of water to produce a final concentration of 44mM?

Question in the title! I’ve tried googling this as much as I can think to; the typical C1V1 solution throws a quadratic that doesn’t match approximated results when I solve it on my calculator. Any help would be appreciated, but especially I’d appreciate help with setting up this kind of problem in general!
