It is found that 1.1 x 10^-6 gram of silver fluoride (AgF) dissolves in 1 L of water at 73 degrees C. Determine the solubility product constant for silver fluoride at this temperature. It is not what is listed on the chart on page 773 because that chart is only for use at 25 deg C.
a. 7.5 x 10^-17
b. 6.2 x 10^-17
c. 8.33 x 10^-16
d. 8.15 x 10^-13
e. 2.02 x 10^-15
