A group of chemists are conducting an experiment to produce a new liquid material. Chemical A contains 15% sodium and the Chemical B contains 30% sodium. They mix the two samples, obtaining 600ml of a new chemical containing 22% sodium.
\n" ); document.write( ".
\n" ); document.write( "Let x = amount (ml) of 15% sodium
\n" ); document.write( "then
\n" ); document.write( "600-x = amount (ml) of 30% sodium
\n" ); document.write( ".
\n" ); document.write( ".15x + .30(600-x) = .22(600)
\n" ); document.write( ".15x + 180-.30x = 132
\n" ); document.write( "180-.15x = 132
\n" ); document.write( "-.15x = -48
\n" ); document.write( "x = 320 ml of 15% sodium
\n" ); document.write( ".
\n" ); document.write( "30% sodium:
\n" ); document.write( "600-x = 600-320 = 280 ml\r
