Sterling silver contains silver and copper metals. If a sterling silver chain contains 33.3 g of silver and 2.70 g of copper, what is the percent of silver

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%

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
