Onsite you notice that the bare soil there feels very compacted. You use a soil bulk density sampler to take a sample of the soil. The sampler you use takes a soil core which takes a soil sample that is a cylinder and has a volume of 85 cm2 . You take a sample, and return it to the lab. As collected the sample has a mass of 170 g. Its oven dry mass is 133 g.  What is the soils bulk density
