Answer:

$111\ grams\ of\ zinc$

Step-by-step explanation:

Let

x -----> grams of zinc

y ----> grams of copper

we know that

$\frac{x}{y}=\frac{3}{17}$ -----> equation A

For y=629 grams of copper

substitute in the equation A and solve for x

$\frac{x}{629}=\frac{3}{17}$

$x=\frac{3}{17}(629)$

$x=111\ grams\ of\ zinc$
