The ratio of zinc to copper is 3 to 13 and a jar of the chemical contains 650 grams of copper. can you tell me the answer : d

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
