Lead compounds are often highly colored and are toxic to mold, mildew, and bacteria, properties that in the past were useful for paints used before 1960. Today we know lead is very hazardous and it is not used in paint, however, old paint is still a problem. If a certain lead-based paint contains 18.1% PbCr2O7 and 82.3% of the paint evaporates as it dries, what mass of lead (in grams) will be in a paint chip that weighs 0.11 g?
