enter your response here grams of zinc.
To find the amount of zinc in the jar, we can set up a proportion using the ratio of zinc to copper.
Since the ratio of zinc to copper is 3 to 13, we can write it as:
3/13 = x/546
Cross multiplying, we get:
13x = 3 * 546
Simplifying, we have:
13x = 1638
Dividing both sides by 13, we find:
x = 126
Therefore, the jar contains 126 grams of zinc.
