A soil with a volume of 163cm^3 is sampled from a field. It weighs 221g. Then, the sample was saturated until the pores were filled and now weighs 273g. The sample was drained and weighed 236g. The sample then sat out for about 2 weeks until at equilibrium and weighed 206g. After oven drying the sample, it finally weighed 202g. What is the percent moisture content by mass (theta g) at field capacity %?
