A solution is prepared by dissolving 23.7 g of CaCl₂in 375 g of water. The density of the resulting solution is 1.05 g/mL. The concentration of CaCl₂is % by mass. A) 6.24 B) 0.0632 C) 0.0594 D) 5.94 E) 6.32

Question

Quizplus · Accepted Answer

The mass percent of CaCl2 is calculated by dividing the mass of CaCl2 by the total mass of the solution and multiplying by 100. The total mass of the solution is 23.7 g + 375 g = 398.7 g. Therefore, the mass percent is (23.7 g / 398.7 g) * 100 = 5.94%.
