1. A soil sample has a specific gravity of solids of $$2.70$$, a void ratio of $$0.90$$, and a water content of $$25\%$$. What is its degree of saturation?
2. If a fully saturated soil has a specific gravity of solids of $$2.65$$ and a water content of $$30\%$$, what is its void ratio?
3. A completely dry soil sample has a void ratio of $$0.50$$. What is its water content?
