1521 grams.

Step-by-step explanation:

It is given that in a certain​ chemical, the ratio of zinc to copper is 4 to 13. A jar of the chemical contains 468 grams of copper.

Ratio of zinc to copper = 4:13

Let the amount of zinc and copper be 4x and 13 respectively.

Copper = 468 grams

Divide both sides by 4.

The value of x is 117.

The amount of zinc is

Therefore, the amount of zinc in the chemical is 1521 grams.
