Modern electroplaters can cover a surface area of 75.0 m² with one troy ounce of gold (volume = 1.611 cm³).What is the thickness of the electroplated gold?

Question

Quizplus · Accepted Answer

The correct answer is A because the thickness of the electroplated gold can be calculated using the formula: thickness = volume / (area * density). The density of gold is 19.32 g/cm^3. So, the thickness of the electroplated gold is: thickness = 1.611 cm^3 / (75.0 m^2 * 19.32 g/cm^3) = 2.15E-8 m.
