Answer:

[tex]\frac{816}{7}\ g[/tex]

Step-by-step explanation:

Let

x -----> the grams of zinc

y -----> the grams of copper

we know that

[tex]\frac{x}{y}=\frac{3}{14}[/tex] -----> equation A

we have

[tex]y=544\ g[/tex]

substitute the value of y in the equation A

[tex]\frac{x}{544}=\frac{3}{14}[/tex]

solve for x

[tex]x=\frac{3}{14}(544)[/tex]

[tex]x=\frac{1,632}{14}\ g[/tex]

simplify

[tex]x=\frac{816}{7}\ g[/tex]
