Arsenic is diffused into a thick slice of silicon with no previous arsenic in it at 1100°C. If the surface concentration of the arsenic is 5.0 x 1018 atoms/cm3 and its concentration at 1.2 m below the silicon surface is 1.5 x 1016 atoms/cm3 , how long must the diffusion time be? (D = 3.0 x 10-14 cm2 /s for As diffusing in Si at 1100°C.)

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?
