The molarity of the dilute solution can be calculated using the dilution formula $M_1V_1 = M_2V_2$, where $M_1$ and $V_1$ are the molarity and volume of the initial solution, and $M_2$ and $V_2$ are the molarity and volume of the final solution, respectively. Given $M_1 = 0.3965$ M, $V_1 = 20.00$ mL, and $V_2 = 900.0$ mL, we find $M_2 = \frac{M_1V_1}{V_2} = \frac{0.3965 \times 20.00}{900.0} = 0.008811$ M.
