\n" ); document.write( "~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "There are 0.06*450 = 27 grams of dissolved salt in the original mixture.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This amount of salt does not change, when we add water to the mixture.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the new volume V must satisfy   = 0.05 grams/mL,   or  V =  = 540 milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It means that 540 ml - 450 mL = 90 mL  of water must be added.      ANSWER\r\n" );
