The average density of whole milk is 1.034g cm -3. What is the density in lb gal-1? Show work.

A paint contains 177.0 ppm lead. Approximately what mass in grams of lead will be in 1.00 cm2 of this paint when 1.00 gal is uniformly applied to 515.0ft2 of a wall. The density of the paint is 8.00 lb/gal.

Ā 
Itried:
8lb/515 ft^2 X 200gPb/10^6 X 453.6 g of paint. Divided answerby2.54 cm per in and then by 12 in per foot. Answerwas .000040918,but incorrect.

Question 3.15: Calculate the density of UO2?

i keep getting 16.85 g/cm^3, but the answer in the back of thebook is 10.9 g/cm^3.

I dont's understand what i am doing wrong.

a=0.474nm

Density = m/V

= ([4(238.030)+8(16.0)]/0.6023*10^24 g /(0.474nm)^3 * (10^7nm/1cm)^3

= 16.85 g/cm^3

What i'm i doing wrong? please help.
