The volume of air in the Erlenmeyer flask for each condition is calculated as follows:
- 0 mL Water Added: \(\boxed{V_0}\)
- 10 mL Water Added: \(\boxed{V_0 = \frac{1.058 \times (V_0 - 10)}{1.000}}\)
- 20 mL Water Added: \(\boxed{V_0 = \frac{1.123 \times (V_0 - 20)}{1.000}}\)
- 30 mL Water Added: \(\boxed{V_0 = \frac{1.197 \times (V_0 - 30)}{1.000}}\)
- 40 mL Water Added: \(\boxed{V_0 = \frac{1.282 \times (V_0 - 40)}{1.000}}\)
