Question #25bc8 Chemistry Solutions Dilution Calculations 1 Answer Al E. Sep 3, 2017 #0.25M# means there is already an aqueous solution of #NaCl#; therefore you need to add #8.0L# of water to make the desired molarity/volume of solution. Explanation: #0.25M * V_1 = 0.2M * 10L# #therefore V_1 = 8.0L# Answer link Related questions How do you calculate concentration from absorbance? How do you calculate concentration from titration?
