How many mL of a 2.00M #H_2SO_4# are needed to provide .250 mole of #H_2SO_4#? Chemistry Solutions Molarity 1 Answer anor277 May 29, 2016 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# Answer link Related questions what is the molarity of 20.0 ml of a KCl solution that reacts completely with 30.0 ml of a 0.400...
