Interpretation Introduction

Interpretation:

Number of lines of IR grating is 90 lines per millimeter and the illumination of this grating occurs at 15.0 mm. First order resolution of this IR grating needs to be calculated and the distance between the two resolved lines is to be determined when they are centered at 1200 cm-1.

Concept introduction:

Formula for the resolving power of grating is as follows:

resolving power=λΔλ=nN

Calculation of distance between two resolved lines can be done using the following formula:

λ=1v¯

3. A 2.50x10-4M solution of a dye has an absorbance of 0.680 when measured in a 1.00 cm cell at 625 nm. Calculate the %Transmittance of the solution. Will the %Transmittance increase or decrease if the concentration of the dye is increased.
The intensity of light passing through a 1.00-cm sample of a solution of polystyrene in methyl ethyl ketone was observed to decrease by O.9%. The concentration of the solution was 10.6 kgm-3. Given A =546.1 nm, no= 1.377, and dn/dC" = 2.20x 10-4 %3D m3/ kg. calculate the molar mass of the polystyrene in kg/mol. The relative displacement (r/ro) of bovine serum albumin was observed as a function of time: t (s) 700 3580 4540 5020 r/r. 1.0129 1.0679 1.0871 1.0965 6 260 /s, find the sedimentation coefficient. Assuming Given w = v = 7.34x 10 3 m3 kg and p = 9.93 x 102 kg/m3, diffusivity = 6.97 x 1011 m2/s at 25 °C, determine the molar %3D mass of the sample in kg/mol.
