The collision flux of a monoatomic gas on copper surface is 3.0 × 10¹⁸ m⁻² s⁻¹. Note that copper surface forms a square lattice with lattice constant of 210 pm. If the sticking coefficient of the atom with copper is 1.0, the time taken by the gas to form a complete monolayer on the surface is s. (Round off to one decimal place)
