A bottle of bleach is opened in a closed room where the air is perfectly still. Estimate how long it will take for the bleach molecules to diffuse through the extent of the room, assuming that the bleach bottle is in the center of the room, and the room is perfectly square, and is a 10 foot x 10 foot room. Assume a bleach molecule has a radius of .15 nm. The molecular weight of bleach (Sodium Hypochlorite NaClO) is 74.35 gms and the room temperature is 300K. Ignore convective currents.
