The size of spherical aerobic bacteria is limited by the rate at which oxygen diffuses through water. A bacterium with a radius greater than roughly 10 µm is not able to obtain enough oxygen from the surrounding water to sustain itself. Given that the diffusion constant of oxygen n water is 8x10^-10 m²s¹, how long does it take oxygen in water to diffuse an RMS distance of 10 µm?
