Hi i need some help with these questions. its for soil chemistry. For question 2, my data is 12 cm and 8cm and then 690 g and 660 g. For queston #3, my data is 167 mg/kg
2. (10 pts) Calculate the moisture content and bulk density of a soil that you sampled using a cylinder (dimensions given in Q2 HW2 DATA) that was pressed into the soil without compacting the soil, then excavating around the cylinder and drying the soil at 105 C The field moist soil collected from the cylinder and the oven dry soil weights are listed in Q2 HW2 DATA. See "Soil Basics" for help. (15 pts) An acre-furrow-slice of soil is the volume of soil that is encompassed by one acre to a depth of 6 inches. A common rule of thumb is that an acre-furrow-slice weighs 2 million pounds. 3. a. Using this information, calculate the bulk density of the soil in English (Ib/ft3) and in SI units (Mg/m3 or Mg m3). What is the mass of a hectare-15-cm volume of soil using the bulk density calculated in part a? What is the mass of Pb (lb and kg) in a hectare-15-cm of soil that contains mg kg 1 Pb? (See Q3 HW2 DATA for Pb concentration) b. c.
