a 3.5L sample of a 5.8M NaCl solution is diluted to 55L.What is the molarity of the diluted solution

all you need to do is first, find the moles of the first solution... 3.5 L x 5.8 M = 20.3 moles...if it is then diluted to 55 L. then all you have to do is divide the moles by the liters to find the resulting M. 20.3 moles / 55 L = 0.369 M. :) hope that helped.
