Answer:
the number of grams of zinc contain is 78
Step-by-step explanation:
The computation of the number of grams of zinc contain is shown below:
Given that the ratio of zinc to copper is 3:16
And, the jar of the chemical has 416 grams copper
So, the number of zinc grams would be
here we assume the zinc grams be x
Now the equation would be
3 ÷ 16 = x ÷ 416
Now applied the cross multiplication
16x = 416 × 3
x = (416 × 3) ÷ 16
= 78
Therefore the number of grams of zinc contain is 78
