Answer: The mass percent of copper in CuBr_2 is 28.45 %.

Explanation:

In CuBr_2, there are 1 copper atom and 2 bromine atoms.

To calculate the mass percent of element in a given compound, we use the formula:

\text{Mass percent of copper}=\frac{\text{Mass of copper}}{\text{Molar mass of copper bromide}}\times 100

Mass of copper= 63.54 g

Mass of copper bromide = 223.37 g

Putting values in above equation, we get:

\text{Mass percent of copper}=\frac{63.54}{223.37}\times 100=28.45\%

Hence, the mass percent of copper in copper bromide is 28.45 %.
