What is the mass percent of fluorine in phosphorus pentafluoride (PF5)?

Expert Solution

p = 30.97 grams

f = 18.998 grams

and in pf5 the fluorine atoms are 5

PF5 has the molar mass => 30.97 + 5 * 18.998 => 125.97 g/mol

mass percent of fluorine => mass of F / total mass * 100

=> 95 / 125.97 * 100

=> 75.4147 %

Phosphorus is diffused into a thick slice of silicon with no previous phosphorus in it. If the surface concentration of the phosphorus is 1 x 10^18 atoms/cm^3, and its concentration at 1 micrometer needs to be 1 x 10^15 atoms/cm^3, after a diffusion time of 1 hour. What is the temperature needed for the process?
