What type of solution forms if 50g of #Pb(NO_3)_2# are dissolved in 100g of water at 20 degrees C?

It quite probably forms a saturated solution.

Explanation:

Nitrates usually exhibit considerable water solubility, i.e.

#Pb(NO_3)_2(s) rightleftharpoonsPb^(2+) + 2NO_3^-#

We know that the solution is saturated if equilibrium quantities of #Pb(NO_3)_2# are in solution. You will have to look up the solubilities of lead nitrate at the given temperature to see that this is indeed the case.
