Benny mixed 12 mL of an acidic solution with 11 mL of a 41% acidic solution, to make 45% acidic solution.
\n" ); document.write( " Find the percent acid concentration of the first solution.
\n" ); document.write( ":
\n" ); document.write( "Let x = the percent of the 12 ml solution in decimal form
\n" ); document.write( "12x + .41(11) = .45(12+11)
\n" ); document.write( "12x + 4.51 = .45(23)
\n" ); document.write( "12x = 10.35 - 4.51
\n" ); document.write( "12x = 5.84
\n" ); document.write( "x = 5.84/12
\n" ); document.write( "x = .4867, 48.67% the percent of the 12 ml solution
\n" ); document.write( " \n" ); document.write( "
\n" );
