\n" ); document.write( "Doreen Schmidt is a chemist. She needs to prepare 32 ounces of a 11% hydrochloric acid solution. Find the amount of 16% solution and the amount of 8% solution she should mix to get this solution.\r
\n" ); document.write( "\n" ); document.write( "How many ounces of the 16% acid solution should be in the mixture?
\n" ); document.write( "


\n" );
document.write( "Let amount of 16% solution to mix, be S
\n" );
document.write( "Then amount of 8% solution to mix is: 32 - S
\n" );
document.write( "Therefore, we have: .16S + .08(32 - S) = .11(32)
\n" );
document.write( ".16S + 2.56 - .08S = 3.52
\n" );
document.write( ".16S - .08S = 3.52 - 2.56
\n" );
document.write( ".08S = .96
\n" );
document.write( "S, or amount of 16% solution to mix = , or  oz
\n" );
document.write( "Amount of 8% solution to mix = 32 - 12, or  oz \n" );
document.write( "

\n" );
