Explain the uncertainty associated with the molar mass

Reference no: EM13533849

The hydroxyquinoline solution used in the Gravimetric Analysis lab was made for you. However, the lab manual explains how the solution was made. THe resulting solution should be about 2.5% by mass hydroxyquinoline. Assume the following is the exact procedure used:

1) 24.5783 grams of pure hydroxyquinoline (C9H7ON) is dissolved in 29.0 mL of HCl and diluted with DI water until the toal volume is 1.00 L (in CLass A volumetric flask). (Density of the solution is 1.008 g/mL)

a) Determine the molar mass of hydroxyquinoline and the uncertainty associated with the molar mass. Report the absolute uncertainty in the molar mass in your final answer.

b) Calculate the molarity of the solution. Report the absolute uncertainty in the molarity in your final answer.
