If 250 ml of a 0.50 m nacl solution is diluted to 840 ml, what is the molarity of the resulting solution?

Explanation:

The given data is as follows.

  = 0.50 M,                 = 250 mL

  = ? ,                         = 840 mL

Therefore, calculate the molarity using the relation as follows.

                =

                  0.50 M × 250 mL = × 840 mL

                                   = 0.148 M

                                   = 0.15 M (approximately)

Thus, we can conclude that the molarity of the resulting solution is 0.15 M.
