mass = volume x density.
mass = 3000 mL x 5 g/mL = ? grams paint.
It contains 10% Pb3N2 so ?grams paint x 0.10 = grams Pb3N2.
A 3L sample of paint that has a density of 5 g/ml is found to contain 10% by mass Pb3N2(s). How many
grams of lead were in the paint sample?

10% of the 15 kg of paint is Pb3N2
find the percentage (by mass) of Pb in Pb3N2
...multiply the result by 10% and by 15kg
