12mL of a 10% ,
\n" ); document.write( "5 mL of 80%
\n" ); document.write( "20mL of a 45%
\n" ); document.write( "..
\n" ); document.write( "total quantity of mixture = 37 ml of x%
\n" ); document.write( "..
\n" ); document.write( "concentration equation
\n" ); document.write( "0.1*12 +0.8*5+0.45*20 = 0.08x*37
\n" ); document.write( "1.2+4+9= 2.96x
\n" ); document.write( "14.2= 2.96x
\n" ); document.write( "x= 14.2/2.96
\n" ); document.write( "x= 4.8 \r
\n" ); document.write( "
