B. What volume of NaOH solution is needed for this reaction?
C. What volume of a stock 1,15M solution would be used to make the solution used in the reaction?

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

Avariable that is not being directly tested during an experiment should be

)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.
