She needs to prepare 32 ounces of a 9% hydrochloric acid solution.
\n" ); document.write( " Find the amount of 16% solution and the amount of 8% solution she should mix to get this solution
\n" ); document.write( ":
\n" ); document.write( "let x = amt of 16% solution
\n" ); document.write( "the total is to be 32 oz, therefore;
\n" ); document.write( "(32-x) = amt of 8% solution
\n" ); document.write( ":
\n" ); document.write( ".16x + .08(32-x) = .09(32)
\n" ); document.write( ".16x + 2.56 - .08x = 2.88
\n" ); document.write( ".16x - .08x = 2.88 - 2.56
\n" ); document.write( ".08x = .32
\n" ); document.write( "x = .32/.08
\n" ); document.write( "x = 4 oz of 16% solution required
\n" ); document.write( "and
\n" ); document.write( "32 - 8 = 28 oz of 8% solution
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this
\n" ); document.write( ".16(4) + .08(28) = .09(32)
\n" ); document.write( ".64 + 2.24 = 2.88 \n" ); document.write( "
\n" );
