Answer: it contains 200 grams of zinc.

Step-by-step explanation:

Ratio of zinc to copper is 4 to 15 = 4;15

Total ratio = 4+15= 19

We first find amount of both zinc and copper( the whole chemical) which is equal to

ratio of copper / total ratio x (the entire chemical--total grams of zinc and copper) =amount of copper

15/19 x X = 750

X= 750 X 19 / 15= 950 grams

To find amount of zinc in the chemical = ratio of zinc / total ratio x total amount of chemical

=4/19 x 950

=200 grams
