So, I have absolutely no clue how to answer this question.  I don't know how to go about doing it.  I would appreciate some help on this.

Lead poisoning from unglazed ceramic vessels has been unfortunately common in the past.  Lead is in insidious accumulating toxin.  The vessel may have been coated with a pigment containing lead chromate (PbCrO4) called 'chrome yellow.'  Suppose a person drank about a quart of water per day (946 mL) of water from such a vessel, every day for 4 years (365 days/year).  Knowing that the solubility product constant (Ksp) for lead chromate is 1.8 x 10^-14, how many milligrams of lead (Pb) will the person have ingested?

Please *delete me*

Use Ksp to calculate solubility of the salt.

How much water would the person drink? Can you calculate amount of lead knowing solubility and volume?
