Answer 1

Answer:168g

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

Answer 2

120 g

Explanation:

Zn:Cu = 3:13

if Cu is 520 gm => Zn = Cu (3/13) = 520 (3/13) = 120
