Homework Help: chemistry

Posted by betsy on Monday, January 26, 2009 at 9:17pm.

If Pdcb replaces naphthalene as an active ingredient in mothballs , what is the value of kf for camphor if a 0.260 m solution of PDCB in camphor decreases the freezing point of camphor by 9.8 degrees C.

I am sure that you will use the formula ^T=-kfm. Since you are given the 0.260m, do you still have to calculate the molar mass for the solution of naphthalene?
