A sample of a substance known to contain chloride ions was dissolved in distilled water in a 1L volumetric flask. Then 25.00 mL of this solution was treated with excess silver nitrate, AgNO3 (aq). The precipitate of silver chloride, AgCl (s) was filtered and dried. The mass of the dry precipitate was 0.765 g.
a. Calculate the concentration of chloride ions.
b. If the original substance was sodium chloride, NaCl (s), what mass of it was dissolved in the volumetric flask?
A balloon equipped with a UV spectrometer was flown in the stratosphere to measure the [O_3] at an altitude of 25 km. The spectrometer had an absorbtion path length of b= 1000.0 m and measured a transmittance of T = 0.6952. Determine the concentr..
