A chemist has a solution that is 50 percent acid. By adding water the solution is reduced to one containing 40 percent acid.
\n" ); document.write( "acid + acid = acid
\n" ); document.write( "0.50x + 0*w = 0.40(x+w)
\n" ); document.write( "-------------------------\r
\n" ); document.write( "\n" ); document.write( "By adding 500cm^3 more water the solution then contains only 35 percent acid.
\n" ); document.write( "0.40(x+w) + 0*500z = 0.35(x+w+500)
\n" ); document.write( "-----
\n" ); document.write( "Comment:
\n" ); document.write( "Your post should contain the amount of 50% solution
\n" ); document.write( "so you could solve for \"w\". It does not so you
\n" ); document.write( "cannot solve for a numerical answer.
