Answer:

percent by mass = 8.0%

Explanation:

Solve for the percent by mass of copper in an alloy.

Note: An alloy is a solid solution. Brass is an alloy of copper and zinc. Copper is the solute and zinc is the solvent.

percent by mass = (mass solute / mass solution) × 100

percent by mass = (8.0 g / 100 g) × 100

percent by mass = 8.0%
