The equation for the best fit line was y = 5532.6x + 20.19. Using the equation of the best fit line, calculate the heat of vaporization (Hvap) and the normal boiling point (in oC) of this volatile liquid. Remember for this experiment pressure is measured in kPa not atm
(Hint: What is the value of Pvap when a liquid boils at its normal boiling point?)
Assume you dissolve 0.235 g of the weak acid benzoic acid, C6H5CO2H, in enough water to make 5.00 102 mL of solution and then titrate the solution with 0.163 M NaOH.
Molecular Orbital theory properly redictsparamagnetism of oxygen gas, O2. This is because a) There are two unpaired electrons in the MO electron configuration of O2

the vapor pressure of pure benzene is 100.84 torr. What is the vapor pressure of a solution made from dissolving 18.4 g of biphenyl in 28.0 g of benzene?
Consider the titration of 30.0 ml of 0.048 M NH3 with 0.025 M HCI. Calculate the ph after the following volumes of titrant have been added.
If 3.55 g of CuSO4 are dissolved in 925 mL of 0.30 M NH3, what are the concentrations of Cu2+, Cu(NH3)42+, and NH3 at equilibrium Kf, Cu(NH3)42+= 1.1 x 1013 . Assume that most of the Cu2+ is converted to the complex since K is a very large number...
