Question 9 Soil placed on a can has been weighed before and after an oven-drying procedure. The procedure yields the following results: 84.4 g. Mass of soil + can before placing in the oven 74 g. Mass of soil + can after placing in the oven Mass of can 33.7 g. If the specific gravity of the soil is 2.82, and the void ratio is 0.567, what will be the moist unit weight (kN/m3) of the soil? Round off to two decimal places.

Someone can help me with this one. Please

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.
