Clearly, it is #0.50*mol*L^-1# with respect to glucose.

Explanation:

#"Concentration"# #=# #"Amount of substance in moles"/"Amount of solution in litres"#.

Given the definition, #"concentration"# necessarily has units of #mol*L^-1#.

So for your problem, we just have to set up the quotient,

#(2*mol)/(4.00*L)# #=??mol*L^-1#. When we set up the problem this way, it automatically gives us the correct units, #mol*L^-1#.
