Answer:

Over #100*mL#.

Explanation:

#"Moles"# #=# #"Concentration"xx"Volume"#. This can be appreciated dimensionally, i.e. #mol*L^-1xxL=mol!#.

We require #0.250*mol#, and so we divide the required number of moles by the concentration to get the volume:

#(0.250*cancel(mol))/(2.00*cancel(mol)*cancel(L^-1))xx1000*mL*cancel(L^-1)# #=# #??mL#
