What quantity of 65 per cent acid solution must be mixed with a 25 per cent solution to produce 672 mL of a 50 per cent solution?
\n" ); document.write( ":
\n" ); document.write( "Let x = qty of 65% solution
\n" ); document.write( "It states that the resulting qty is to be 672 ml, therefore
\n" ); document.write( "(672-x) = qty of 25% solution
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation
\n" ); document.write( ":
\n" ); document.write( ".65x + .25(672-x) = .50(672)
\n" ); document.write( "Find x \n" ); document.write( "

\n" );
