<PRE><B>Question 856041</B>
WANT:  {{{(100*(1/1000)gram*matter)/(1000grams*mixture)=(1/10000)grams*matter)/(1*gram*mixture)}}}


AVAILABLE:   {{{0.5*grams*matter/(100*grams*mixture)=0.005(grams*matter/(grams*mixture))}}}


If wanted 100 grams of the mixture, then you are to dilute some quantity of the concentrated suspension.
{{{((0.5/100)*w)/(100)=1/10000}}} and w is how many grams, might be very small, of the suspension to use, for 100 grams of the mixture.


SOLVING:
{{{(0.5/10000)w=1/10000}}}
{{{w=(10000/0.5)(1/10000)}}}
{{{highlight(w=0.5)}}} grams of the concentrated suspension; work the contents up to 100 grams total with water.</PRE>
