In an experiment similar to Perrin's, you counted the concentration of suspenc particles in a liquid. When observing the suspension at a depth 9 mm from th bottom of the container, you counted 300 particles per mm. At a depth of 18 from the bottom, you counted 150 particles in the same volume. With a third observation at a depth of 20 mm from the bottom, the expected number of pa per mm3 is closest to which value?

In an experiment similar to Perrin's, you counted the concentration of suspended
particles in a liquid. When observing the suspension at a depth 9 mm from the
bottom of the container, you counted 300 particles per mm. At a depth of 18 mm
from the bottom, you counted 150 particles in the same volume. With a third
observation at a depth of 20 mm from the bottom, the expected number of particles
per mm is closest to which value?
100 particles per mm3
64 particles per mm3
O particles per mm3
130 particles per mm3
