Answer:

Approx. #3xx10^-3# #mol*L^-1#

Explanation:

#"Concentration, molarity"# #=# #"Moles of solute"/"Volume of solution"# #=# #(1.56*mol)/(500*L)# #=# #??# #mol*L^-1#.

By doing the calculation this way and including the units, I am introducing a reality check on my calculation. Do the resultant units make sense? Well, they are not #L*mol^-1# but #mol*L^-1#, as is required for a concentration.
