Question 7 (
A carefully-weighed 53.2 gram soil sample was dispersed for particle-size analysis
using the Bouyoucos hydrometer method. The laboratory was held at a constant
temperature of 20 C (68 F). If this soil sample contains 95 % of sand-sized particles
by weight, then the 40-second hydrometer reading will be:

Question 8
The tin (Sn) content of soils ranges across several orders of magnitude. The log(mg
kg1) for one soil sample (that is, the Sn content in [mg Sn (kg soil)*1], is found to be
log(mg kg1) = 2.22. What is the tin content of the soil in [mg Sn (kg soil)-²]?
