Chapter 14, Problem 14B.4E

Interpretation Introduction

Interpretation:

From the given data, the surface excess has to be calculated.

Concept Introduction:

Surface excess: Amphiphilic molecules accumulate at the water–air surface with their hydrophobic tails exposed to the air to minimize interaction with the water. Their accumulation at the surface relative to the bulk is called as surface excess.
