Your calculations look correct.
The equation you want is:
C1V1 = C2V2
Where C1 and V1 are your starting concentrations and C2 and V2 are your final concentrations.
C1 = 40 g/L, V1 = ?, C2 = 0.04 g/L, V2 = 1 L
rearrange to get V1 by itself 0.04*1/40 = 0.001 L or 1 ml.

Thank you for response. I will learn more of the C1V1 calculations but your explanation makes it pretty clear.
