Sample Soil Water Problems

A soil sample at the field moisture condition weighed $420g.$ It weighed $364g$ when it was air dry. After oven drying the soil, it weighed $350g.$ Calculate the percentages by mass of water in the original field moist soil and when the soil was air dry.

$\%$ Water by mass at field moist condition $=\%$ Water by mass at air dry $=$

What is the oven dry mass of a $560g$ soil sample containing $25\%$ water by mass?

Oven dry mass $=$

A uniform soil to a depth of $20cm.$ contains $32\%$ water by mass and has a bulk density of $1\mathrm{.}48\frac{g}{c}{m}^3$

Calculate the $\%$ water by volume. $\%$ water by volume $=$ Calculate the $cm.$ of water held in the top $20cm.$ of this soil. $cm.$ of water held $=$
