  • question_answer 48)   If 500 mL of a 5 M solution is diluted to 1500 mL, what will be the molarity of the solution obtained? (a) 1.5 M                              (b) 1.66 M (c) 0.017 M                          (d) 1.59 M


      (b) \[{{M}_{1}}{{V}_{1}}\] (concentrated) = \[{{M}_{2}}{{V}_{2}}\] (diluted) or  \[5\times 500={{M}_{2}}\times 1500\] or  \[{{M}_{2}}=1.66\]
