I have a mixture problem to find 15 milliliters of a solution that is 2% active ingredient and I have a 10% and 1% solution in my stock.
\n" ); document.write( "How do i get 2% solution?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of 10% solution
\n" ); document.write( "The resulting amt is to be 15 ml, therefore
\n" ); document.write( "(15-x) = amt of 1% solution
\n" ); document.write( ":
\n" ); document.write( ".10x + .01(15-x) = .02(15)
\n" ); document.write( ".10x + .15 - .01x = .3
\n" ); document.write( ".10x - .01x = .3 - .15
\n" ); document.write( ".09x = .15
\n" ); document.write( "x = $\".15%2F.09\"$
\n" ); document.write( "x = 1 $\"2%2F3\"$ ml of 10% solution
\n" ); document.write( "and
\n" ); document.write( "15 - 1 $\"2%2F3\"$ = 13 $\"1%2F3\"$ ml of 1% solution \n" ); document.write( "

\n" );
