How many milliliters of water must be added to 12 ml of a 60% salt solution in order to produce a 42% salt solution? Round your answer to the nearest tenth.
\n" ); document.write( "-------
\n" ); document.write( "Equation:
\n" ); document.write( "salt + salt = salt
\n" ); document.write( "0*x + 0.60*12 = 0.42(x+12)
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "0 + 60*12 = 42x + 42*12
\n" ); document.write( "42x = 18*12
\n" ); document.write( "x = 5.14 ml (amt. of water needed)
