Calculate the molarity of the solution produced by mixing 31.0 mL of 0.180 M NaCl and 80.0 mL of 0.150 M NaCl. (Assume that the volumes are additive.)

Explanation:

Hello,

In this case, a mixing process is carried out, so the molarity should be modified by considering the new volume of the solution after mingling, in such a way, the resulting moles are:

Afterwards, the total new volume of the solution is:

Finally, the new molality is:
