Question 902011
From a practical point of view, adjusting from 3% to 0.1% only makes sense if the correct amount of sorbic acid was used but much of the water was omitted accidently (like someone forgot to add it).


{{{3*300/(v+300)=0.1}}}


Understanding that equation is important.  If you do  not understand that equation, then you may want help for THAT.


If you do understand, then just solve for v.
