in chemistry class, 9 liters of a 4% SILVER IODIDE solution must be mixed with a 10% solution to get a 6% solution. how many liters of the 10% solution are needed?
\n" ); document.write( "-----------------
\n" ); document.write( "4% solution DATA;
\n" ); document.write( "Amount = 9 liter ; amt of active ingredient = 0.04*9= 0.36 liter
\n" ); document.write( "---------------
\n" ); document.write( "10% solution DATA:
\n" ); document.write( "Amount = x liter ; amt of active ingredient = 0.10x
\n" ); document.write( "-----------------
\n" ); document.write( "6% Mixture DATA:
\n" ); document.write( "Amount = 9+x liter; amt of active ingredient = 0.06(9+x)=0.54+0.06x liter
\n" ); document.write( "======================
\n" ); document.write( "EQUATION:
\n" ); document.write( "active + active = active
\n" ); document.write( "0.36 + 0.10x = 0.54 + 0.06x
\n" ); document.write( "0.04x = 0.18
\n" ); document.write( "x = 4.5 liter (amt of 10% solution that must be added to get the mixture)
\n" ); document.write( "==================
\n" ); document.write( "Cheers,
