Question 780936: A goldsmith mixed 10 g of a 60% gold alloy with 40 g of a 25% gold alloy. What is the percent concentration of the resulting alloy? (Round your answer to the nearest percent.) i'm not sure how I should solve this at all? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! A goldsmith mixed 10 g of a 60% gold alloy with 40 g of a 25% gold alloy.
What is the percent concentration of the resulting alloy?
:
A typical mixture equation, the total result will be 10+40 = 50 mg
let x = the decimal form of resulting percent
:
.60(10) + .25(40) = 50x
6 + 10 = 50x
16 = 50x
16/50 = x
x = .32, result is 32% gold alloy
