Question 995710
First mixture:
{{{(40*8+60*12)/100=10.4*percent}}}, and this is 100 milliliters of solution.


The Next mixture:
v volume was removed and replaced with distilled water, and this now became 5.2% acid.  Find v.
{{{(100*0.104-0.104v)/100=0.052}}};
Volume of starting solution stays the same 100 milliliters; just the concentration changes; this equation is setup in decimal fractions instead of percents.  Solve for v.
