Question about question 4 in lab 05

Fragment of a discussion from Course talk:APBI403

Bill, from question 3 you know the concentration in the soil mg/kg i.e. mg of element x / kg of soil. Question 4 asks you to extrapolate that concentration (mg/kg) over 1 ha area (20 cm deep) assuming a soil bulk density of 1200 kg/m3. Since your answer to question 3 is in mg/kg of soil you need to use the bulk density of the soil in question 4.

But Dylan told me not to use bulk density... I am confusing...
