document.write( "\r\n" );
document.write( "stating that the pure acid amount is the same in ingredients and in the mixture.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "x =  = 75 mL.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.  0.5*300 + 75 = 225 mL of the pure acid.\r\n" );
document.write( "\r\n" );
document.write( "        0.6*(300+75) = 225 mL of the pure acid.    ! Correct !\r\n" );
