Question 403751
if i need to add {{{25 ml}}} of acid to {{{600 ml}}} of water 

what percent of acid does this give me?


{{{25 ml}}} is {{{x}}}%={{{x/100}}} of {{{600 ml}}}

so, {{{(x/100)600 ml = 25 ml}}}.....solve for {{{x}}}

{{{(6cross(0)cross(0)cross(ml)*x/1cross(0)cross(0)) = 25 cross(ml)}}}

{{{6*x = 25}}}

{{{x = 25/6}}}

{{{x =4.17}}}%
