Answer:

We ASSUME that a #100*mL# volume of SOLUTION contains a #1.5*g# mass of solute..........

Explanation:

And thus #"molarity"# #=# #"Moles of solute"/"Volume of solution"#

#=((1.5*g)/(278.10*g*mol^-1))/(0.100*L^-1)=5.4xx10^-2*mol*L^-1#.

Lead chlorides are pretty insoluble. A solution of this concentration may represent a saturated solution.
