150 grams of zinc is present
Solution:
Given that, ratio of zinc to copper is 3 to 13
A jar of the chemical contains 650 grams of copper
From given information,
zinc : copper = 3 : 13
Let the zinc present be 3x
Let the copper present be 13x
Given that, jar contains 650 grams of copper
13x = 650
x = 50
Substitute x = 50 in 3x
Zinc present = 3x = 3(50) = 150
Thus it contains 150 grams of zinc
