In a 1-D particle tracking experiment, you observe that after 60 seconds, the particles you are following have a mean square displacement of 6.3 µm2. If the temperature of the room is 18 °C and the hydrodynamic radius of the particle is 500 nm, what is the viscosity of the solution? Write your answer in Pa • s (kg m-1 s-1).   Remember that kB=1.38⋅10−23kB​=1.38⋅10−23.
