WANT:

AVAILABLE:

If wanted 100 grams of the mixture, then you are to dilute some quantity of the concentrated suspension.
%28%280.5%2F100%29%2Aw%29%2F%28100%29=1%2F10000 and w is how many grams, might be very small, of the suspension to use, for 100 grams of the mixture.

SOLVING:
%280.5%2F10000%29w=1%2F10000
w=%2810000%2F0.5%29%281%2F10000%29
highlight%28w=0.5%29 grams of the concentrated suspension; work the contents up to 100 grams total with water.
