please help this is quantitative analysis

If a solution containing 34.26g of lead(II) perchlorate is allowed to react completely with a solution containing 5.102g of sodium sulfide, how many grams of solid precipitate will be formed? mass of solid precipitate: Incorrect How many grams of the reactant in excess will remain after the reaction? mass of excess reactant: Incerrect Assuming complete precipitation, how many moles of each ion remain in solution? If an ion is no longer in solution, enter a zero (0) for the number of moles. Assuming complete precipitation, how many moles of each ion remain in solution? If an ion is no longer in solution, enter a zero (0) for the number of moles. Pb2+ mol
