You are working in a lab and are tasked with determining the percent plant available water for a particular soil sample. You take a field soil sample. The mass of your sample was 152g and it had 18.3% moisture by mass. Then, you place the soil sample in your pressure plate extractor and determine that the soil sample weighs 164.2g when the moisture potential is -33kPa and 130.7g at -1500kPa. What is the percent plant available moisture by mass of this soil sample? Please answer to one decimal place.
