Question 208959
26.0 grams of silver, 10.8 grams of tin, 2.4 grams of copper, and 0.8 grams of zinc
.
Total weight = 26.0 + 10.8 + 2.4 + 0.8 = 40 grams
.
Of the total weight, 26 grams is made up of silver Or
26/40 * 100 = 65%
.
So, if you have 25 grams of analgam, 65% would be silver:
.65 * 25 = 16.25 grams
