a compound was analyzed and found to contain C,H,N,O, and Cl. When o.150g sample of this compound was burned, it produced 0.138 g of CO2 and 0.0566 g of H2O. All of the Nitrogen in another sample of mass 0.200 g was converted to 0.0238 g of NH3. Finally,...

An estimation of the radius of a lead atom: a. You are given a cube of lead that is 1.000 em on each side. The density of lead is 11.35 g/cm3. How many atoms of lead are contained in the sample. b. Atoms are spherical; therefore, the lead atoms in this sa...

Recently, there has been much concern about pollution in the home from radon, a radioactive gas whose elemental molar mass is 222 g/mol. The Environmental Protection Agency say that a level or radon of 3.6 X 10-11 giL of air is unhealthy. At this level, h...

is suppose to be V=4pir^3/3 sry. I get part A. but part B and C are confusing!

ok i got the answer but seem different i get C3H6Cl2 N O

Its suppose to be 3.6e-11g/L

what i ended up doing was got 3.6e-11g/L(2455L)= 8.838x10^-8g/2455L then, 8.838x10^-8g converted them into moles then into atms. right or wrong?
