Answer:

[tex]111\ grams\ of\ zinc[/tex]

Step-by-step explanation:

Let

x -----> grams of zinc

y ----> grams of copper

we know that

[tex]\frac{x}{y}=\frac{3}{17}[/tex] -----> equation A

For y=629 grams of copper

substitute in the equation A and solve for x

[tex]\frac{x}{629}=\frac{3}{17}[/tex]

[tex]x=\frac{3}{17}(629)[/tex]

[tex]x=111\ grams\ of\ zinc[/tex]
