I assume you are referring to lead as in the elemental form (Pb metal), in which case it's 683.1 g
The equation tells you that for every 2 moles of water you need 1 mole of lead.
Molar mass of water is 18 g/mol. 119 g of water is 6.6 moles.
So you need 3.3 moles of lead. The atomic weight of lead is 207 g/mol, so you need 3.3 x 207 = 683.1 g.
