Argon crystallizes in the face-centered cubic arrangement at 40k. given that the atomic radius of argon is 191 pm, calculate the density of solid argon.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

plasma - state of matter made up of electrically charged particles
