a lab technician has 8 liters of a 15 percent solution of acid. How much distilled water must be added to reduce the concentration of acid to 10 percent?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of distilled water, (0% solution)
\n" ); document.write( ":
\n" ); document.write( "Write a % solution equation:
\n" ); document.write( ".15(8) + 0(x) = .10(x+8)
\n" ); document.write( ":
\n" ); document.write( "1.2 + 0 = .10x + .8
\n" ); document.write( ":
\n" ); document.write( "1.2 - .8 = .10x
\n" ); document.write( ":
\n" ); document.write( ".4 = .10x
\n" ); document.write( ":
\n" ); document.write( "x = .4/.1
\n" ); document.write( ":
\n" ); document.write( "x = 4 liters of distilled water required \n" ); document.write( "
\n" );
