A solution is formed by adding 2.70 grams of solid sodium hypochlorite, NaClO, to 200.0 ml of 0.0210M calcium hypochlorite, Ca(ClO)₂. Calculate the pH of the resulting solution. You may assume that the sodium hypochlorite dissolve completely and that the change in volume is negligible with the addition of the solid.
