The concentration
of a solute (in units of atoms·mm⁻³) in a solid along
direction (for
) follows the expression
where
is in mm,
and
are in units of atoms·mm⁻⁵ and atoms·mm⁻⁴, respectively. Assuming
, the magnitude of flux at
mm is _____ ×
atoms·mm⁻²·s⁻¹ (answer rounded off to the nearest integer).Given: diffusion coefficient of the solute in the solid is 3 ×
mm²·s⁻¹.Log in to check the answer
