Approximately $66.7 m L$ $66.7mL$ of the concentrated bleach solution, diluted to $400 m L$ $400mL$ with water will produce the desired concentration for your cleaning pleasure.

Explanation:

We're given a desired volume and concentration, and a current concentration, to relate these variables, I'll use the equation,

$M_{1} V_{1} = M_{2} V_{2}$ $M_1V_1 = M_2V_2$

Hence,

$400 m L \cdot \frac{L}{10^{3} m L} \cdot 0.5 M = 3 M \cdot V_{2}$ $400mL * L/(10^3mL) * 0.5M = 3M * V_2$
$therefore V_2 = 66.7mL$
