Suppose small, spherical pieces of pasta are floating in a column of water at a temperature of 298 K, in an experiment similar to Perrin's. Using a microscope, you are able to count the number of pieces of pasta per litre. You position the microscope at a height of 6.0 cm above the bottom of the water column and you count 130 pieces of pasta. You next move to a position that is 15.0 cm above the bottom of the column, and you count 65 pieces of pasta. How many pieces of pasta would you find 20.0 cm above the bottom of the column?
