Calculating Water Volume and Saturation

For 2018 Midterm, how to solve question 1 part d? Can you assume particle density =2.65? The question did not mention that it is a mineral soil. Also, is the question asking for volumetric water content? It doesn't specify?

Hi Wanyue To answer Q1d) on the 2018 exam, you can indicate "assuming a mineral soil, and a particle density of 2.65"

You are correct, the question is not clear. As long as you provide units and indicate whether you are determining gravimetric or volumetric water content either answer would be correct.

Let me reiterate - that the calculation question on the 2018 midterm was particularly challenging.
