    Answer:168g

    Step-by-step explanation:

    The ratio of zinc to copper is 4 : 13

    Copper = 546g ( from the question)

    let zinc = x

    so therefore

    Zinc : copper

    4 : 13

    X : 546g

    Then cross multiply

    13X = 4 × 546g

    13x = 2184g

    X= 2184g/13

    x= 168g

    Given –

    In a certain chemical, the ratio of zinc to copper is 4 to 13.

    The chemical contains 546 grams of copper.

    Prove  –

    How many grams of zinc does it chemical contain.

    Answer

    suppose that scalar multiple of the  zinc and copper be y .

    As given

    In a certain chemical, the ratio of zinc to copper is 4 to 13.

    The chemical contains 546 grams of copper.

    Than equation is

    13y = 546

    13y = 546

    y = \frac{546}{13}

    y = 42

    Zinc contain in the certain chemical = 4y

                                                  = 4 42

                                                  = 168 grams

    Therefore 168 grams of zinc contain in a certain chemical .
