You can put this solution on YOUR website! A silversmith mixed 25g of a 70% silver alloy
= 17.5 gm of silver (25*0.7)
-----------------
with 50g of a 15% silver alloy.
= 7.5 gm of silver (50*0.15)
--------------
What is the percentage concentration of the resulting alloy?
17.5 + 7.5 = 25 gm of silver in a total of 75 gm
--> 1/3 = 33.33...% silver
