Answer:
Mass of copper in 200 g bronze is 120 g.
Explanation:
If it is known that bronze is formed with 60% copper and 40% tin, what will be the mass of copper contained in 200 grams of bronze?
Percentage of copper in bronze = 60 %
Percentage of tin in bronze = 40 %
Mass of bronze = 200 grams
Mass of copper in bronze = 60 % of 200 g
= 0.6 x 200 = 120 grams
Mass of copper in 200 g bronze is 120 g.
