Structural formula for octanediol


H2C2O4 + 2NaOH -> Na2C2O4 + 2H2O


if n(H2C2O4*2H2O) = 6.44*10-6, what is the amount of NaOH in moles?


1. (a) State Graham’s law of diffusion
(b) Arrange the following gases He,CH4,and N2 in order of increasing rates of diffusion, give reasons for your answers. [H = 1,He = 4,C = 12,N = 14]
2. 60cm3 of hydrogen diffused through a porous membrane in 10 minutes. The same volume of a
gas G diffuses through the same membrane in 37.4 minutes. Determine the relative molecular
mass of G. [H = 1]
