The mass percentage of chloride ion in a 25 ml sample of seawater was deteremined by titrating the saample with silver nitrate , precipitating silver chloride. it took 42.58 ml of 0.2997 m silver nitrate soltuion to reach the equivalence point in the titration. what is the mass percentage of chloride ion in seawater if its density is 1.025g/ml

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
