Need help with deciding what formulas to use for this question please

100.00 inI of Pb ( NO ) 2(29 ) ( unknown molarity ) is treated by adding 50.00 mI of solution which has800 M Nal ag) and 3 320 8 of KI( ) ( which has subsequently dissolved ) . 18 410 8 of precipitate isI precipitatallected by vacuum filtrationi . Determine the concentration of each iononce the precipitation process is complete , and determine the initial molarity of the lead II nitrateAssume the individual volumes are additive , and that the volume does not change when precip -itation occursit . If an excess of silver nitrate was added to the filtrate , what mass of which precipitate would nowbe formed ?
