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
[tex]y = \frac{546}{13}[/tex]
y = 42
Zinc contain in the certain chemical = 4y
= 4 42
= 168 grams
Therefore 168 grams of zinc contain in a certain chemical .
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
