You can put this solution on YOUR website! A silversmith mixed 40 g of a 70% silver alloy with 75 g of a 15% silver alloy.
What is the percent concentration of the resulting alloy?
(Round your answer to the nearest tenth of a percent.)
:
Let x = percent of resulting alloy
70(40) + 15(75) = x(75+40)
2800 + 1125 = 115x
3925 = 115x
x =
x = 34.1 %
