Interpretation Introduction

**(a)**

**Interpretation:**

The density of solution I_{2} is 0.794gm/cm^{3} which is present in ethanol. Transmission of 33.2% of the radiation from a Mo Ka is done by using a layer of 1.50 cm. Mass absorption coefficient are 39.2,0.70, 0.00, 1.50 for I, C, H and O respectively. Percentage of I_{2} present in ethanol is to be determined, neglecting the absorption by alcohol.

**Concept introduction:**

Formula used for the calculation are-

Where,

P_{o}= transmitted beam power

P = incident beam power

µ_{M} = mass absorption coefficient

ρ = density

x = sample thickness

Where,

_{2} W= weight fraction of iodine

Interpretation Introduction

**(b)**

**Interpretation:**

Percentage of I_{2} present in ethanol is to be determined when alcohol is present.

**Concept introduction:**

Formula used for the calculation are-
