: A student mixed 50 ml of a 3% hydrogen peroxide solution with 30 ml of a 12% hydrogen peroxide solution. Find the percent concentration of the resulting mixture. Round to the nearest tenth percent.
\n" ); document.write( ":
\n" ); document.write( "Let x = the decimal amt of the resulting mixture
\n" ); document.write( ":
\n" ); document.write( "Write a simple decimal equation:
\n" ); document.write( ".03(50) + .12(30) = x(50 + 30)
\n" ); document.write( ":
\n" ); document.write( "1.5 + 3.6 = 80x
\n" ); document.write( ":
\n" ); document.write( "80x = 5.1
\n" ); document.write( ":
\n" ); document.write( "x = 5.1/80
\n" ); document.write( ":
\n" ); document.write( "x = .06375 * 100 = 6.4%
\n" ); document.write( " \n" ); document.write( "
