TableVolume of liquid, ml 8.30mass of cylinder & liquid, g 45.00mass of graduated cylinder, g 38.44Solubility: in water iin cyclohexane sboiling point, °C 80
(1) Calculate the density of the unknown liquid?
(2) List the liquids in table 2 whose densities and boiling points most closely match those of the unknown liquid. List these liquids densities, boiling points, & solubilities.
(3) Based on your evaluation of all of the data in your answer to (2), including solubilities, identify the unknown liquid. Briefly explain your reasoning.
Provide the following information for a titration analysis involving a titrant and titrand, where the titrand is a weak, diprotic acid (Ka1 = 1.00 x 10-4; Ka2 = 1.00 x 10-8; Vol=0.01000 L; FH2A=0.1000 M) and the titrant is a strong monoprotic base..
