An infinitely sharp zone of solute is placed at the center of acolumn at time t = 0. After diffusion for time t1, the standard deviation of the Gaussian band is 1.0mm. After 20 minutes more, attime t2, the standard deviation is 2.0mm. What will be the width of the band after another 20 minutes, at time t3?
