The Atomic Mass of silver is 107.868 and the atomic mass of chlorine is 35.453. Therefore, the fraction by mass of silver in silver chloride is 107.868/(107.868 + 35.453) or 0.7526. The precipitated silver chloride therefore contains 0.7526 X 6.21 or 4.674 grams of silver from the coin. The mass percent silver in the coin therefore is 100(4.674/6.80) or 68.7 % silver, to the justified number of significant digits.
