A silversmith mixed 25g of a 70% silver alloy
\n" ); document.write( "= 17.5 gm of silver (25*0.7)
\n" ); document.write( "-----------------
\n" ); document.write( " with 50g of a 15% silver alloy.
\n" ); document.write( "= 7.5 gm of silver (50*0.15)
\n" ); document.write( "--------------
\n" ); document.write( " What is the percentage concentration of the resulting alloy?
\n" ); document.write( "17.5 + 7.5 = 25 gm of silver in a total of 75 gm
\n" ); document.write( "--> 1/3 = 33.33...% silver
