In chemistry class, 5 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( "Equation:
\n" ); document.write( "iodide + iodide = iodide
\n" ); document.write( "0.04*5 + 0.10x = 0.06(5+x)
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "4*5 + 10x = 6*5 + 6x
\n" ); document.write( "4x = 2*5
\n" ); document.write( "x = 2.5 liters (amt. of 10% solution needed)
