Calcium chloride, CaCl2, is commonly used as an electrolyte in sports drinks and other beverages, including bottled water. A solution is made by adding 5.00 g of CaCl2 to 60.0 mL of water at 25°C. The density of the solvent at that temperature is 0.997 g/mL.

Calculate the mole percent of CaCl2 in the solution.

Express your answer as a percent to three significant figures.
