One gram of pbcl2 is dissolved in 1.0 l of hot water. When the solution is cooled to 25degrees Celsius, will some of the pbcl2 crystallize out? If so, how much?
I just don't know where to start/ where to go with this problem
Any help is appreciated!!

Look up Ksp for PbCl2 and solve for solubility PbCl2 @ 25 C. (You will get solubility at 25C because that temperature is used for determining Ksp).
Then convert M to mols/L, then to grams/L. If the solubility is >1.0 g no ppt; if < 1.0 g, yes a crystallization will occur.
