document.write( "40 milliliters of the 5% salt solution contain  40*0.05 = 2 grams of dissolved salt.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You want to dilute it to 2% concentration by adding pure water.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Let new volume after adding pure water be W milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You want the concentration   =   be equal to 2%, i.e. 0.02:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     = 0.02.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It implies  W =  = 100 milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the new volume should be 100 milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that you must add  100-40 = 60 milliliters of pure water to get your goal.     ANSWER\r\n" );
