H2SO4 + LiOH Li2SO4 + H20 a) If 75.4 mL of a 6.00 M sulfuric acid are put in a beaker, how many grams of solid lithium hydroxide would be needed to neutralize it?
b) If 75.4 mL of a 6.00 M sulfuric acid are put in a beaker, how many milliliters of a 4.5 M lithium hydroxide solution would be needed to neutralize it?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
