Pentaerythritol tetranitrate (abbreviated PETN, chemical formula C5H8N4O12) is an explosive material with a structure that is very similar to nitroglycerin. It is one of the components of plastic explosives such as Semtex. The explosion of PETN can be represented by: C5H8N4O12(s)→2CO(g)+4H2O(g)+3CO2(g)+2N2(g) A plastic explosive charge is formed into a cylinder about 30 cm long and about 2 cm in diameter. It weighs about 276 grams and is 58.5% PETN by mass. What is the total number of moles of gas produced when this plastic explosive charge explodes?

Estimating the radius of a lead atom. (a) You are given a cube of lead that is 1.000 cm on each side. The density of lead is 11.35 g/ cm3. How many atoms of lead are in the sample? (b) Atoms are spherical; therefore, the lead atoms in this sample cannot fill all the available space As an approximation, assume that 60% of the space of the cube is filled with spherical lead atoms. Calculate the volume of one lead atom from this information. From the calculated volume (V) and the formula (4/3) 3 for the volume of a sphere, estimate the radius (r) of a lead atom.
