Answer:
7.5 % of Ag
Explanation:
Total mass of sterling silver chain is:
Mass of silver + Mass of copper
33.3 g Ag + 2.70g of Cu = 36 g
% of Silver is (mass of silver / total mass) . 100 →
(2.70 g / 36 g) . 100 → 7.5%
Answer:
92.5 % is silver
Explanation:
Step 1: Data given
Mass of silver = 33.3 grams
Mass of copper = 2.70 grams
Step 2: Calculate the total mass
Total mass = mass silver + mass copper
Total mass = 33.3 grams + 2.7 grams
Total mass = 36 grams
Step 3: Calculate % silver
% silver = (mass silver / total mass )*100%
% silver = (33.3 grams / 36.0 grams) *100%
% silver = 92.5 %
92.5 % is silver
