What is the new mass/volume (m/v)% of a KOH solution that is prepared by diluting 110 mL of a 6% (m/v) KOH solution to 330 mL?
A)2%
B)1%
C)6%
D)12%
E)18%

The initial mass/volume percentage is 6%, and the solution is diluted to three times its original volume (from 110 mL to 330 mL), so the concentration is reduced to one-third, resulting in a 2% (m/v) solution.
