    Equilibrium concentrations and total pressure question.

    I understand about 90% of how to do this question. The only problem I'm having is understanding how volume comes into the calculations. My solution manual has it where; 0.186mol / 2.16L to find the initial concentration for H3CON and then volume is not brought into calculations of finding x...

    Depth of penetration: Attenuated Total Reflectance

    Hi, I am having some trouble calculating the depth of penetration of light at 1725cm-1 in a polymer with refractive index 1.5 at an angle of incidence of 45o. The ATR crystal used is made of KRS-5 and has a refractive index of 2.37 at 1000cm-1. The equation is: dp = λ/{2 pi n1 √(sin2θ –...
