A 200-mL volume of NaOH solution was addedto 400mL of a 2.00 M HNO2 solution. The pH of themixed solution was 1.5 units greater than that of the original acidsolution. Calculate the molarity of the NaOH solution.
The vapor pressure of pure liquid A at 300K is 575torr and that of liquid B at 300K is 390torr. The molar volume of A is 0.0262L/mol and that of liquid B is 0.0306L/mol. Calculate the final partial pressures of A and B in the gas phase.
