Question 1 Calculate the molar solubility of silver chloride in
the following solutions: (Ksp = 1.6 x 10-10)
a) In pure water
b) In 0.10 M FeCl3
Question 2
The density of a solution is determined using a class A 25-mL
volumetric flask and an analytical balance. If the mass of the
empty volumetric flask is 26.9872 ± 0.0003 g, the mass of the flask
filled with solution is 53.9820 ± 0.0003 g. The absolute
uncertainty associated with the reading of this class A flask is ±
0.03 mL.
a) Calculate the density (g/mL) of the solution
and give the answer with correct number of significant figures.
b) What is the absolute uncertainty for the density? (With the correct number of digits)
