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.
Compute the pH of the resulting solution. I got 3.87 if you mix 250 mL of 3 M benzoic acid and 500mL of 1.5 M sodium benzoate, Explain what is the expected pH of the buffer? I got 7.19 I just need someone to check if my answers are correct.
